Germans demonstrate how windows, of all things, separate European life from American life
Who knew this was such a cultural difference?

Stoßlüften is the German tradition of replacing the air in the home several times a day.
We may share some significant historical and cultural roots, but Americans and Europeans also have some distinct differences in the way they do things. There are the big things for us Americans like how we handle healthcare and young children doing active shooter drills at school, but there are also little things like how generous we are with ice and free soda refills.
And then there's something most of us probably don't think of as a difference, but apparently is: windows.
For the most part, in the U.S., windows are just…windows. You look out them. You clean them sometimes. When the weather is not too hot, not too cold, and not too windy or rainy, you open them for a while to get some fresh air.

In Germany and many other parts of Europe, window culture is an entire thing. First, windows have a tilt-open-from-the-top option that you rarely ever see in America. And second, Europeans use their windows actively, opening and closing them daily, all year round, regardless of the weather. And in Germany, it's not just daily, but multiple times a day.
Watch the creators at Radical Living humorously demonstrate this cultural difference by acting out someone learning about German windows from their first day in the country through 10 years of living there.

Stoßlüften literally means "shock ventilation" and refers to the German habit of replacing stale air with fresh air, which Germans do several times a day, every day. Yes, even in the dead of winter.
The discussion in the comments of the video is hilarious, as Europeans say they just thought this was normal and Americans (and apparently Australians?) are agog over the tiltable window design.
"I actually didn't knew that in other countries they had no tiltable windows. I just thought every country would have these."
"In Turkey, we call windows that open from the top 'vasistas.' The word comes from the German phrase 'was ist das,' which means 'what is this.' A bit silly, but really funny."
"I'm Australian. I had no idea windows that open on both axes existed. This is the first time I've ever seen this concept."
"My hotel in Italy had a tilting window like this, and until today I really thought that window was broken this whole time. Glad I didn’t complain to the front desk. That would have been embarrassing haha."

"Used to live in Switzerland, and it is so true! You need to air out the kitchen and whole apartment during winter more often. The heater and closed room, mixed with our own body heat, gives off a very moist and warm feel in the room, which means more mold growing."
"I'm an American and do this during the winter too. My grandfather was German, maybe this is why I do it."
"I married a German woman. I LIVED THIS EXACT CHARACTER ARC."
If you're an American reading this, your first reaction to opening all the windows in winter is probably, "Doesn't that do a number on your heating bill?" Most of us get chastised just for leaving a door open longer than a few seconds in winter. According to some, it's not as much of an energy suck as you might think, since the change of air helps regulate humidity levels and it's only a short time that the windows are open.

As Carrie Bradon writes in House Digest, "While you may find that the air in your home feels a bit chillier following a Stoßlüften session, the limited amount of time that the indoors are exposed to outdoor temperatures is short enough to keep all of the walls, floors, and furnishings from getting frigid. This means that it will take limited energy and time to get your home back to your ideal indoor temp."
However, at least some of the American reactions to this idea and the European normalization of it has to do with the age of our homes. Europe has a lot of very old buildings that don't have the kind of ventilation systems newer buildings in America have. Air really does get stale there in ways that it rarely does in most U.S. homes.

Americans are also accustomed to right-down-to-the-Fahrenheit-degree climate control in our homes. Not everyone, of course, but many Americans have full HVAC systems with heating and air conditioning that blows through ducts with air filters and return vents and whole house fans, which not only circulate the air but keep it exactly the temperature we prefer. Whole house air conditioning is much less common in Europe, and heating in older buildings is often radiant heat, fueled by natural gas that heats water that gets pumped into radiators. So naturally, using windows for air purification and ventilation would be more necessary in Europe than in the U.S. and sensitivity to indoor temperature fluctuations may be less pronounced.
Still, getting fresh air into our homes on a more regular basis isn't a bad idea, and experts recommend opening windows at least once a day for 5 to 10 minutes—yes, even in winter. Looks like we should follow Germany's lead on this one, fellow Americans.
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."
