People from other countries share 14 'obvious' signs that someone is an American
"Americans lean on anything they can while standing around…"

Some American tourists enjoying the sights
Americans have a style and personality all their own, which isn’t a bad thing. It’s just noticeable when they travel aboard. Americans often stand out because of their outgoing personalities. They are friendly and enjoy having casual conversations with strangers.
This is an endearing trait to a lot of people in more reserved cultures, although it can also come off as a little brash.
An American characteristic that isn’t quite endearing to people in other countries is that they can be rather loud. In Europe, one can always notice the Americans in the restaurant because they can be heard from across the room.
A Reddit user named Frosty-Ad3575 wanted to know the specific ways that Americans stand out when traveling abroad, so they asked the AskReddit subforum: “What’s an obvious sign that someone is an American?”
The post was popular, receiving nearly 6,000 responses in just 6 days. The most popular ones described how Americans' unique personalities, style of dress, dental hygiene and body language make them easy to spot.
Here are 14 “obvious” signs that someone is an American.
1. Posture
"Apparently, the CIA trains American agents to not lean on things if they go undercover in foreign countries because Americans lean on anything they can while standing around." — Clown1998
"I bet MI6 trains British agents to lean on everything if they go undercover in America because Americans lean on anything they can while standing around." — KingoftheMongoose
2. The date
"MMDDYYYY." — LowRevolution6175
3. Distances are different
"Anything under 4 hours is 'close by.'" — Grey-Canary
"Everything in Europe is around the corner if you're from the US. I can drive the whole day and not leave my state, but in Europe, I can pass through 4 countries in that same time frame." — JayHitter
4. They're polite to servers
"In the touristy cafe-restaurant I worked at:
If they asked me for the nicest spot we had
If they asked me my recommendation without seeing the menu first
I would walk to the table, and they would say right away ‘hey, how are you doing?’ This one threw me off a lot at first. Why is this person asking me how I'm doing?? I'm just there to take the order. I got used to it, and I think they found my awkwardness cute.
They would ask my name when I greeted them and took their order.
I'm Northern European." — Muc_99
"It’s under-appreciated just how polite, friendly, and sincere Americans are in general. It blew my mind the first time I came to the US, and I love that my children are growing up with those same values." — Irishweather5000
5. The water bottles
"I was told, 'Americans carry water bottles around like they're worried they'll never have access to clean water ever again.'" — Kosher_Dill
"I don't care what anyone says. If you think carrying a water bottle when walking a lot is weird, you're probably slightly dehydrated all the time and are just desensitized to it. You seriously need to drink water frequently if you want to be ideally healthy." — Tan11
6. Smiling
"I was in Germany this past summer, and I realized smiling at everyone you make eye contact with is very American. When I went to London on the same trip, they seemed less weirded out by it but would awkwardly return the smile. I was taught to always start with a disarming smile. Never realized it was American." — 12ozFitz
7. "More ice, please."
"I spent a year in Europe completely iceless to the point I forgot that was a thing. I stopped at a bar in Chicago fresh off the plane and not only did I get free tap water, but water with ice. I instantly felt at home." — Outside-Crezz8119
8. Personal space
"As an American man, I’ve been told repeatedly by European and Asian friends that we simply take up space (not by being fat) as though we’re entitled to it. Men in other countries apparently don’t claim the same personal space we do." — Potomacan
9. White teeth
"It’s even more bizarre that they assume we have braces or bleach our teeth because they’re straight and white. I have naturally straight white teeth. I brush them twice a day so they stay white. I don’t do anything special to them, but I remember being in London and some similar-aged students literally making fun of me for my teeth… it’s true that they don’t naturally look like headstones in an ancient graveyard, but there’s no need to make fun." — DPretilloZbornak
10. Casual dress
"My friend went to Germany recently, and what people said about Americans is you can spot them a mile away because they’re the ones wearing pajamas in public. Apparently, in other countries, at least Germany, they dress a little more formally and in less baggy clothes than we do in America." — MarcusWahlbezius
11. Baseball hats
"Baseball cap... even on an infant riding in a pram." — SyntheticOne
12. Shoes
"Americans are shoe snobs (they don’t think they are, but they are). Setting aside wealthier business types, Americans generally wear more on-brand, on-trend, high-quality shoes than others." — Mouflony
13. They're loud
"That was my first thought. Americans yell at each other in normal conversation in public. I noticed it years ago in Europe, and now I can’t stand it in the US." — SucccotashOther277
14. Occupation matters
"Immediately asking someone what they do for a living when meeting them. Our jobs and work are our entire identity." — Bealzu
"I hate that about American culture. I'm an American and recently became a SAHM, so I don't have an answer to 'What do you do for a living?' Half the time, I add the caveat, ‘Oh, my last job was with Apple,’ so that I'm not written off as an unemployed ‘loser.’ But it really is dumb to determine a person's worth by what they do in order to afford food and shelter." — WassupSassySasquatch

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
