I can be downright nasty if I get really, really pissed. But I think its partially because I don't let it all out when it comes and I can somehow accumulate a lot of resentment. Plus I don't usually get really, really pissed.
Don't think I've fought with a F but maybe with my sister who is a T.
I think the way T's fight are a little more detached and downright cold whereas F's may fight indirectly.
