Yeah, you are right. Could have been months ago, could be leftover. Who knows. Even if it is something going on now he realizes it is wrong. I really don't think it is something going on now though.
Oh yeah, meant to comment on the aggravating part. He kept messing with me last night (tickling me and just kind of being annoying). I just said "Why are you aggravating me so much?" He said "that is the way I show my affection". I am not sure why he felt the need to bring it up in the email unless he thought I was frustrated with him because of it. I wasn't, but maybe it came off that way.
