George H: It isn't just with him, but it does happen with him a lot since he's the person I've been spending the most time with lately. He's amazingly understanding. He doesn't care if I breathe on him, but I still can't stop the compulsive monitoring of my breathing in which I will hold my breath, turn my head, then breathe when I'm not facing anyone. It's extremely irritating. :/
