Well, I once got in a fight with my "friend". Over a TV show character, i know it sounds odd- She said she'd block me if i liked him, and later she payed my brother to tell her my secret, and well she blocked me.
I actually had another friend who acted like that, and well she's not my friend anymore.
Explanation:
MORAL OF THE STORY: People who do that were never your friends in the first place.
