I've mentioned this before but for the first Christmas after I got married, my MIL gave me a pair of washing up gloves and some American tan sheer tights. She said they went together as a sexy outfit.
I was so so embarressed. She had also, without telling us, invited a couple she was friends with. They brought us gifts and we had nothing to give them back. Then she corralled them into doing most of the cooking.
After lunch she had a long loud phone call with DH's ex wife.
We don't spend Christmas with her any more.
