Seriously though, anyone from anywhere can be cool/fun, but some stereotypes do hold true. For ALTs almost half of them are tiresome for me because they're just acting like they're in college and talking about the same 3 topics the whole time. Plus the circlejerk of misconceptions about Japan from ignorant people is very tiring.
Otherwise I just like spending time with chill people, really. And most British ALTs seem to be incredibly tense/awkward to me, whereas a lot of ALTs from elsewhere are much more open and relaxed. Might just be something I notice being from England myself.
I think I could hang out with most people on here because they're fairly interesting and though we moan about living in Japan a bit the forum atmosphere beats most of the super stereotypical/dumb complaints out of people fairly well.
