I don't do very well in packed rooms. My wife's family (decent people) like packing everyone they can get their hands on into a small living room for any excuse they can come up with.
Christmas with them starts at 1:00 PM today at my sister-in-law's house (24th) and runs through supper at my mother-in-law's Christmas day. I bailed out early tonight.
I really felt bad when the kids were young. They'd get to open their gifts then we'd drag them away to be with wife's family. I'd have rather had them enjoy Christmas day at home.
