My Grinch today was strong and I didn't entirely hide it successfuly.
Oh, Jesus. I love Tim's family, and Christmas dinner was nice with them, but it got to be too much, especially when it came time to clean up. Some of us were in the (medium-size) kitchen trying to put leftovers away and wash dishes, and 2 nephews and an uncle (Tim's brother; i.e., old enough to know not to do this) came tear-assing into the kitchen with this tabletop pinball game thingy to play the game in the kitchen "because it's the only room with good lighting."
Tim's SiL (wife of the brother who was playing the damn game) came in the kitchen and saw them playing and asked them, "Are you helping clean up?" and I didn't even let them answer before I said, without turning around, "Actually, what they're doing is the EXACT OPPOSITE of helping clean."
They were cleaning within 90 seconds. I feel kind of bitchy in retrospect, mostly because it wasn't my own family. Had it been my family, I wouldn't have even bothered with snark; if anyone in my family came in the kitchen to play a game while I was trying to clean, they would have gotten punched in the neck and then told to cope with the pain while they cleaned.
I opted against actual assault on my boyfriend's family. At least this year.
Honestly, it was 99% a good time, although I am dog-ass tired. But the shenanigans were poorly timed.
