I saw that Dateline episode. Sorry for your sister but if that didn't convince her. . . I guess I'd be a bit pissed if my computer were wrecked by someone else though, that might be enough for me to say "enough" :-)
I'm getting ready to make apple crisp and brownies. I have to find an easy quiche recipe too for breakfast on Christmas morning. I bought a huge ham half in case I get invited to my stepsister's but I think they've gone to the Caribbean on vacation for the holidays. I only see her/them (my step-nieces/nephews and their children) once a year, Christmas Day so am out of any loop that might exist. Good thing we live near one another!
Anyway, I'll do something with the ham myself for Christmas. We have a friend with no friends or relatives at the moment other than us and jobless to boot coming over so we'll just eat on the darn thing ourselves. I figured I'd make biscuits and we can have ham sandwiches and bought a bottle of champagne, etc. Leftovers I'll freeze and use the bone for soup for New Years.
