So I know I'm being unreasonable, I just need to be told to give my head a wobble.
I have a lovely MIL, kind, caring, helpful with our kids. I am very lucky. Mothers day is also her birthday and she wants to go out for lunch. My mum passed away a few years ago so she's the only mum in that generation.
DH has said we can do something for me on Saturday and I'll get the morning for presents etc from the kids. It's not even a real day and my MIL has a real birthday.
So I need to be told to not be grumpy about it, and to go with good grace and make it a nice day.
