People are sharing the 'telltale sign' that someone is a selfish person. Here are 17 red flags.
“When people show you who they are, believe them.”

"Who me?" A woman asks if she is selfish.
In 1997, Oprah Winfrey spoke with Maya Angelou for an “Oprah’s Lifeclass” episode, and she revealed one of the most important lessons the “I Know Why the Caged Bird Sings” author had taught her: “When people show you who they are, believe them.”
“When a person says to you, ‘I’m selfish,’ or ‘I’m mean,’ or ‘I am unkind,’ believe them,” Oprah says in the clip. “They know themselves much better than you do.”
Oprah recounted the life advice while discussing a relationship with a man she felt had let her down. “[Dr. Angelou] was saying to me, ‘Why are you blaming the other person? He showed you who he was,'" Oprah recalled.
Angelou’s simple advice is a great way to detect potential red flags, whether someone has a new romantic partner, coworker or friend. It’s especially helpful when we’re unsure of how to judge someone or in denial about their questionable behavior.
A Reddit user with the username Potatoe_stealer asked the online forum, “What is a telltale sign that someone is a selfish person?” and the question received over 7,000 responses. Many of them explained how selfish people often disregard others in conversations or downplay the seriousness of their problems.
This is a great way to determine if someone will be selfish when a conversation turns into action. According to this group of Reddit users, if someone is cutting you off when you speak, they may not be there for you when things get rough.

"They respond how worse their situation is when you’re sharing your problems with them. No try for help or listening, just trying to draw attention on their side." — seyfgs
5.
"They gladly take any favours you do for them, but when asked if they could reciprocate once, they get defensive and or aggressive and act like you're the selfish one for daring to expect something in return. It doesn’t make you a bad person to expect reciprocation in a relationship with someone else, romantic or platonic. Relationships are give and take and that makes them healthy. It's not entitlement to expect kindness if you give kindness. If you're the only one giving, you're being taken advantage of." — random-sh**-writing

"Every bad thing you do to them is drama-worthy. Every bad thing they do to you are details and should be moved on from, and why can't you just do that? You're so dramatic!" — Pasdusername

"If you are in a group and there is one person that is constantly interrupting the middle of what you or anyone else is saying generally to brag about themselves with a 'one-upper' story, is generally a precursor to stop associating with them. I've met too many of them in my days and they are more often than not happy to throw you under the bus whenever the opportunity arises." —Philay_shio

"If they always talk about themselves." —Effective-Craft-1173

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
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."
