egad, some people get so completely unglued at the prospect of celebrating Christmas on any other day than the 25th- and i don't get why!! Geez it seems like christmas already lasts the entire month of December- who cares if you get together on the 24th, 25th or the 29th?? it really all feels the same to me, doesn't it to you??
anyway,. I'd make a mention on how YOU didn't schedule the surgery date- YOU aren't performing the surgery, you are at the mercy of the surgeons and the hospital schedule yeesh.
Pod. Even if surgery isn't an issue, multiple celebrations on Christmas Day to keep the peace among the extended family can be too much to handle for a lot of people (both children and adults). It's much more pleasurable and less stressful to spread things out a bit and be able to fully enjoy everything for what it is, at the time, than cramming multiple, rushed visits, and probably multiple large holiday meals, all into one day. Seriously, I really don't see what's fun about waking the kids up at the crack of dawn, making them leave the presents they just got from "Santa," packing them into the car, and then taking them to Grandma's for Christmas morning, Aunt Margaret's for Christmas lunch, and Uncle Murgatroid's for Christmas dinner, while remembering to bring the correct gifts and potluck contributions for people at each house, and packing gifts from THEM into the trunk for the drive home, and explaining to little Johnny five thousand times that no, he CAN'T play with his K'nex set from Uncle Murgatroid yet, because you don't want all the pieces to go missing before you get home (and having to deal with the ensuing tantrum), and THEN inevitably having to call a steam-cleaning service on the 26th to clean partially-digested turkey from the inside of your car, because the toxic relatives INSISTED that Johnny and Tziphaknee "try a bit of everything," and accused them of being "ungrateful" even though they already had stomach aches?
