"Guilty" of something and he's afraid you are going to find out about it,so he's trying to let you know before you hear what he did,that he's a bad person.

Good luck with finding out. And one more thing Surf Movies
Well, HERE'S an idea..... ASK 'im

Good luck with finding out. And one more thing, men tend to hide things under the bed.
tell him to kill himself
How about you ask him why he feels this way and be there for him?
