I'm the same way. Pranks are pointless. They just make the other party feel bad.My personality doesn't blend well with April Fools jokes. I do not get pleasure out of embarrassing or scaring others and I have never seen a practical joke that I thought was funny. Just me, I guess! It wasn't just when I matured either, I hated it as a kid as well.
No, your right, sometimes I'm not much fun at parties!
