I've seen some wearing wintercoats

An Australian family moved to my town on some kind of exchange and yah, the one kid was still wearing a jacket at 30. Literally never wasn't cold.

Taught us how to play cricket, he was a cool kid.

as someone who has visited one of the hottest countries on Earth, yeah... 30C in countries like that, is considered chilly. There were a couple of days in a row where the temp reached 50 and kept crawling. My Scandinavian ass was not ready.

Tbf, I do that
