when the man is unreasonably nice to me. It puts him on morally superior ground and we all know how competitive I am about that space.
(While this was in draft, I came out and asked him why he was being so nice and he explained that since I was down it would only be a matter of time until I started planning to leave him, and he was hoping that if he were nice to me I'd take the boy. HAH! I take back the moral superiority. Unlike him, I was being nasty without any ulterior motive whatsoever.)
