Why do they hate leftovers? They eat nothing but t.v. dinners? This is what we have to look forward to? I hope not! OP here. Sorry to come across as a wise guy, but everyone does notice it and everyone does seem pretty inconvenienced by it.
Also, we are trying to teach our young children that we eat what is served, so bringing special food for them is kind of a huge change in the wrong direction. I think she thinks kids don't eat?
In other words, we want to come, and we'll be glad to change our plans, but at what cost? Pitching in would be easy, I guess I just expect some communication. Since that is not going to happen, I really appreciate the suggestions, thank you! If we didn't have kids, we probably wouldn't even care.
She is definitely like this in other ways, so I really, really appreciate the support. Maybe she is a 1950's housewife who maybe enjoys having a rather arbitrary say? I understand FIL was like this, so I imagine it was not a great atmosphere, altogether. DH says she was always set in her ways and most of the time, never really made sense, and DH (thankfully) is not so much this way. DH is accustomed to there not being enough food, sadly. He feels like she is too old to change now, which is fine. She hosts because she seems to enjoy it (though not quite sure, maybe she doesn't)? Maybe she just likes to have everyone together? She is not really involved in the family, so maybe this is her way of trying to make amends? Perhaps it is for appearances? It only happens a couple times a year, and we are trying to enjoy everyone (even when they are tired, hungry and cranky).
Keep those productive suggestions coming, I really appreciate it. When we go elsewhere this has never come up, we bring a dish and some bottles of wine and everyone enjoys themselves. So as I said, it is kind of perplexing - I don't know that our usual dish and bottles of wine would cover it, but we can try.
When we host we try to set an example, but clearly that is not a consideration.
I do realize this is not a big deal in the grand scheme of things. I am just trying to make it so that our children will want to visit their grandmother, since she doesn't really see them otherwise. She had offered to babysit for DH's birthday (once per year, we don't ask). For dinner, she wanted to give our son an apple, even though we left freshly prepared dinner choices and veggies/sides in the fridge.
Come to think of it, I think she has a food issues....
