I would do the same thing I would do if we had not gotten into a fight - go straight to the hospital.
I don't really fight with my friends. Nick and I get super annoyed with each other, but we just take an hour or so off from each other and then we're fine. Missy and I got in a "fight" once, but we just needed a break and then we just kind of found our way back to each other. Katie and I get into little arguments, but then we talk it out. Maybe when you're 32 the fights stop? Because honestly even the people I used to kinda fight with I don't anymore. I'm just too tired to waste energy fighting with people.
