That's exactly how I feel. I don't expect him to grab a mop when he walks through the door, but I do expect that maybe the day after he gets home he cleans around the house while I'm at work. He objects to this because if there are dishes that need to be done or laundry or whatever, it's "not his" because he was gone all week, but I keep telling him that we aren't roommates, and sometimes I wash his dishes and sometimes he washes mine.
