The way I've interacted with people in my family and with friends most of the time, I haven't held back from aggression. Neither have they. It just didn't bother us. If someone was mad, it was just like, ok, big deal. If they piss you off, you tell them off. Whatever, not that serious ... people get in fights, screaming matches, sometimes they're just not particularly polite, and you reciprocate, and then it's done. The girl I'm with right now can barely deal with it if I give her a cold look or an angry gesture when I get mad about something - so I don't. All anger just comes from hurt anyways; that having been acknowledged, I've trained myself so that when something upsets me (regarding her), I express vulnerability, instead of dangerousness. It's been an interesting exercise in behavioral modification and it's honestly not that hard now that I'm used to it. However, I do still sometimes find it refreshing to talk to people who can express anger and who can deal with anger. So fuck you.
