Well, I try, but everybody just has one type of person that really gets under their skin, no matter what. Yeah, well, this person was that person for me, and I found it oddly difficult to keep my temper. Mostly because she had no logical arguments whatsoever, preferring to resort to 'I'm right because you suck and you don't speak Japanese.'
It's annoying. We always ended up swearing at each other, and we were both far too stubborn to concede we were wrong (which we both usually were), but it was still fun.
