The outlaws (who are wonderful) asked if they could come to us for Christmas. My mother came last year and seems to think that she has the right to come when she wants - on the only other occasion we've spent Christmas with the outlaws (in 14 years of marriage) she has called me "shit as a daughter". She went away with a friend that year, had a massive falling out with her and cracked her head open (long story) and said "That wouldn't have happened if I'd come to you." (nice)
I have to tell her - somehow - that the outlaws are coming to us, and brace myself for the stream of vitriol on my failings as a daughter. Should I have a word with her sister first, to see if she might have her (they don't particularly get on but she might take pity on me!)
