"One last thing you ought to think about - come to agreement with your husband about what answer he is to give when asked "Where is LeeLee?". Because he will be asked when he shows up alone. "
Oh, I have a line for this one! My DH is an introvert and I've lived in several environments where everyone was expected to show up to frequent gatherings, potlucks, etc. My DH has excellent boundaries and has never felt guilty about just skipping when he needs to, whatever people think--but I was getting pretty annoyed for awhile that *I* had to deal with all the "Where is DH?" comments. (On a side note I also developed a pet peeve about the word "anti-social" during this time. Started to want to make a general announcement: People, "anti-social" means criminal tendencies. The word you are looking for is UNSOCIABLE.)
I finally hit on the solution:
Sociable Person: Thistlebird, where is Mr. Thistle?
Thistlebird: At home.
(Said in a tone that implies I am confident this is a full and satisfactory answer to the question.)
No one asks me where he is anymore!
