Never get on my bad side.
Once you’re on my bad side, you’re going to be there for a very long time. Even if time has passed, I will still remember the reason why I disliked/hated you. I know I said I hate fighting - but that’s only if you’re my friend. If you’re someone I’m not close to and you’re going to be a cunt to me, I’m going to hate you for a very, very long time.
Forgive and forget? Sorry, I don’t do that for dickheads.
