I ended up with my first hot tea ever by ordering tea in Mexico, as I would have in Texas. I was very confused when I got a mug of water and a tea bag. I was 15-ish. I'd literally never heard of anyone drinking tea hot. (This was in the mid-90s, so reading stuff on the internet wasn't much of a thing.)

Europeans, on the other hand, seem to be baffled by the concept that iced tea is just, you know, cold black tea, not a soft drink you buy at the store. I've seriously had people ask me how to make it.
