I get on fine with my MIL but today I have just had enough of her bossiness in my house.
I think that she may be passive aggressive in the extreme; I will be washing up, she will come behind me and shout say: 'Stop doing that! I'll do it!' or I'll be in the middle of making a cup of tea and it's 'You sit down, I'll do it.'
I know that it sounds benign but when you feel that you can't do anything in your own home without getting shouted at, you get a bit worn down. I know that she means well.
When coming to stay she will phone up to ask if they should bring their own bedding, towels, and food, despite the fact we live in a nice flat with all our own furniture, crockery, bedding etc etc, and within walking distance to a Tesco.
I am a relatively well educated and competant woman. I can make a cup of tea in my own house!
