"I know they treated you like shit, but that doesn't mean that you get to drive off and start your new life while I spend a night in the hospital because you decided to treat them like shit back."
This is now what keeps me from doing some not-nice things when I am frustrated. I don't want to be that person who treats someone bad when they treat me bad. For the most part, I can say that I've tried to be that person. I have slipped up. I am human. But I am also trying to be a better human.
