What should I do if I want to get into a fight to let my pent up aggression out?
Isn't there a better way to let out pent up aggression?
Sure we could talk it out, but I would rather hit someone.
It isn't nice to hurt someone.  If you need a release, talk or write a journal entry.
I'm going to get so worked up that I might hit you.
Being aggressive is seen as a negative trait so you may want to avoid getting to the point of aggression. It  would be best to let out your frustration through exercise or another physical activity.
