I know this has been brought up by other girls, so I thought to post mine.
Wife: Please dress up when we get home.
Me:[blink, blink] huh? Not sure about that, got stuff(painting, walk the dog, yadda yadda yadda) to do. [pause] You've never asked before. What brought this on?
Wife: You've been kinda crabby to everyone lately. I want you to be nice for awhile.
Me: Um.... OK. [Rearranging tasks for indoor to-do list]
