I meant both, but I tend to have more first hand experience with questions. So that's why my examples were like that.

Like the making assumptions thing. I've been watching a lot of documentaries about Japan recently, and one of them was about money and how it's given as a gift on special occasions. Several people took this to mean Japanese people don't give other kinds of gifts at all. So I got kind of annoyed at that lack of common sense.

Or the whole "the age of consent in Japan is only 13 lol" shit. I always have to correct people on that because they assume that means you can fuck 13 year old kids over there, which you CAN NOT.
