This question came up while discussing holiday plans with a co-worker..
His family switches off hosting a Christmas breakfast each year, between 3 or 4 adult siblings. Generally, whoever is hosting provides all of the food. While some of the smaller sides may vary, he said that for years the traditional meal has been country ham, biscuits and sawmill gravy, scrambled egg casserole (they use the same recipe every year), and french toast.
He said that this year, it's his sister's turn to host, and she's decided to change the meal. She's having honey ham instead of country ham, "doesn't like" making gravy so is skipping it, and not doing the french toast either. CW said that they all look forward to the country ham and sawmill gravy all year, and it won't feel like Christmas without it.
I'm a little torn on this.. on the one hand, it is certainly the host/hostess's right to determine the menu. However, since this is something that is a family tradition, and is always the same meal just with a different host, I think it was a little thoughtless of the sister to just decide to change it up without consulting the sibs.
