My MIL and I have had the usual kind of relationship over the years, she thinks the sun shines out of her sons arse and I'm not good enough for him. She came to visit yesterday/today and whilst I was at work she cleaned my house. (She has a history of making snidely remarks about cleanliness/cooking etc etc. my DH thinks that I am totally overreacting but I see it as another dig. What are your thoughts?
