So.....my mil and I and my DH have a long horrid back story. Its childs party today and the first thing mil does when she walks in is rearrange a throw ( she gave us many xmasses ago) on our sofas, and then puts another throw over another chair? 
I came in - saw it and and moved it. I could hear her grumbling t FIL and when I came in again, it was spread over it again. I personally dont like throws like that! Its like student digs!
Who would bloody well do this?????? Is she spoiling for a fight? Is she thick?
Shall I go to her house armed with blankets and decide to better her house??????
She was a nightmare in other ways too - but I felt this was the biggest personal transgression!
