I live near a university that attracts quite a few international students/lecturers and I’ve often witnessed the exact opposite of this. You’re outside in the middle of summer, trying not to die of a heat stroke, when a obviously non-native person walks by wearing a winter coat and a hat.
Yep I saw some Indians near Atlanta who were wearing big coats when it was just a hair below 70 F outdoors. I was out there loading stuff into my car in shorts and a T-shirt and they looked at me funny.
The opposite of that, that I also saw was my portly Eskimo friend, who was in shorts and a T-shirt in the actual winter time when I needed a big coat. He was like "You think this is cold?"
It was 50 last night when I took the dog for a walk. I was too lazy to put on socks, so it was in sweats with sandals and bare feet. Was surprisingly easier on the feet than I expected
I mean room temperature is 20 °C (68 °F) so wearing shorts and T-shirt should be the norm imo. If it isn't colder outside than inside, why put on more clothes?
Believe it or not, I'm also from Sweden, and most people I know have it set to 19-20, and one guy 18. I've never seen 23(!) I can't believe they're native Swedes.
When I visit friends in northern Germany they also run around like it's summer when it's close to winter cold for me.
I had a friend jump into the North Sea to rescue a beer crate we put into the water for staying ice cold that swam away. While I was freezing on two blankets near the fire in a coat.
That beer was also too cold. None of their behaviour made any sense.
All over Asia every time the temperature in the evening goes from scorching to bearable for me, everybody there starts pulling out sweaters and jackets.
That was me, I live in the tropics near the mountains where you can go from 42⁰ at crazy humidity near sea level to 15⁰ up around 2000m in about an hour's drive. I lived near sea level and when we were kids we'd meet halfway with friends who lived in the mountains. They'd be running around in just swimsuits and I'd be sitting on the side wearing 3 layers.
This is me. I have had people say I make them sweat by looking at me when I wear a sweater in 75F just because it’s not yet hot enough to make me take it off.
