HereForTheBeer: Crash it!
I can't. It's MY party. Kind of. I run a B&B with my folks, think Bonanza without the horses, Every year we have this Christmas bash, but I'm petrified of any room that has more than 4 people in it so every year I barricade myself upstairs. Incidentally that is why I will be lounging around this forum all night, sorry.
Funny fact. The town we live is has a year round population of 44, yet we average 250 people every year at this party. They must warp in from another demension.
