Slapping my ex hard across the face when he came over to my house uninvited and tried to ask for my forgiveness after he deliberately made out with my best friend in front of me as "revenge" on me for dumping his sorry cheating ass.
I know that isn't really awesome but nobody will ever understand how good it felt to do that. Plus I don't think I've ever done anything "awesome" in my life to be honest. I swear, my life puts an emphasis on the term "plain Jane".
I definitely understand. I had an abusive boyfriend once who loved to try to intimidate me whenever we were fighting. One time he wouldn't leave when I told him to, he just stood there blocking the door like he wasn't going to let me leave, so I just hauled off and punched him in the mouth. What makes it even better is that he's a Marine and I'm about five feet tall. But, I know how to punch. He left after his lip started bleeding. So yeah, I kinda know how you feel on that one.
