Is it wrong that I messed up my friend's hookup a few days ago and I thought it was funny.
What was so funny about messing up your friend's hookup?
Because I've never done this kind of thing before and the feeling was exciting.
You shouldn't involve yourself in your friend's relationships just to get a cheap thrill and some attention from them. You should instead stay out of thier love life and be there for them when they need it.
I'm a big kid so I'll do what I want.
Getting involved in your friend's relationship is wrong and will interfere with the connection they are trying to form. It will also completely damage your friendship.
