The point I'm trying to make is that I am the most unpleasant, rude, ignorant and all-round obnoxious arsehole that anyone could possibly have the misfortune to meet. I am dismissive of the virtuous, unaware of the beautiful and uncomprehending in the face of the happy. So if I didn't understand I was being asked to be best man, it is because I never expected to be anybody's best friend.
