Why do I keep embarrassing himself around him?

No, it's okay. People embarrass themselves all the time. Put yourself in his position, if a friend did this to you you would just shrug it off wouldn't you? I would, so does he probably. You haven't done anything to embarrass yourself. I have a similar problem but like.. Ten times worse. I liked this girl so much but kept embarrassing myself around her. I randomly fainted while talking to her and knocked myself unconscious, resulting in having to be carried out of the lesson a stretcher. A few days after that a bird decided to s�hit on me whilst having a conversation with her. Then a week after that I was talking to her again and a tennis ball flew out of no where and whacked me in the face. I am totally accident prone and embarress myself a lot, you just have to learn to laugh it off. You can't hear the world laughing at you if you're laughing harder.
