I probably am...
MiL likes getting all her children and grandchildren together at her house for the day. I like it too, it's always good to catch up with the extended family and for the cousins to play together. But - and I know this is irrational - I can't abide the fact that she insists on calling them a Family Day. With capital letters. Grrrr.
I could live with this (just about) because I know it's my problem to deal with. But I am really struggling with the fact that she is trying to make it an annual fixture on the same weekend every year - and not linked to eg her birthday. A couple of years ago I (very politely) said that we have lots of other things going on, and didn't want to commit to an annual fixture, and I thought she had taken this on board. But the email summoning the clan has just come out, confirming that "the Family Day will be on X, as usual".
How do I respond? I don't want to say we aren't going, because our DC would miss out on seeing their family. But if we just go, then we are by default signing up to an annual Family Day. Which I really really don't want to do. I also don't want to cause a rift with a MiL I get along with really well.
DH would be quite happy not to go, BTW, and I talk to MiL far more than him.
Help me navigate this one, oh wise MNers!
PS is a Family Day a thing other families do, or something MiL has created?
