3 Mothers in law, 2 (along with their sons) are deceased. Both of them were AWESOME, it was their husbands I had a bit of trouble with! William's mother is only 10 years older than I am, and what a wonderful woman she is!! I clean when I know she's coming, but I don't think she'd say a word if I didn't.
Funny how all 3 fathers in law were jerks....and all 3 women are/were terrific!
My own mother? Heh! I didn't clean when she was coming, it gave her something to do and bitch about while she was there! ;) :)
