Am I freaking over nothing?

I'm the kind of guy that's all for the laughing and the having fun. But I invited 3 of my friends over and I ended up Falling asleep. So during my hour sleep they took a king size sharpie and drew all over my face. In addition they completely messed with my iPod. Took pictures and I don't know if they got any farther then my one friends email( it's ok he left his email open and I deleted them). So right now their up stairs playing on y PS3 while I don't k ow if I should just suck it up and go up stairs or just ignore them. Help?
