I'm going to laugh at my ex
Why are you going to laugh at him?
He was such a loser and he can't be happy without me
You don't have to be friends with an ex but you shouldn't laugh at him. It will hurt him and people will think that you are vindictive.
What is wrong with laughing at him. It sucks being him. Haha
You seem like you are hurt by that ex, but it's still not good to turn around and laugh at him.
