Having it at my folks house. My Bumpa (grandfather) will be on the couch watching football and spouting right wing propoganda (LOVE U BUMPA!), Nana will be drunk on gin and it's our job to keep her situated in a chair without falling.
Then the neighbors/leeches show up. My parents are upper middle class in a rural area, lots of people are simple farmers or milkmen and such. My mom is a bit of a free spirit and welcomes anyone in to her house pretty much anytime, so there will be Paul the 55 y/o aspiring actor there to regale us with stories about his "buddy" and "old confidante" Jimmie Spader or his lunch with Tom Hanks (meaning he was an extra on a movie that Hanks was in, and they fed him buffet style while Hanks had lunch with the governor, more likely). Then there's Cinda, she'll act like she has something better to do than drink our scotch and eat our food. Something like milking goats or braiding garlic.
After that, there's my 5 brothers and sisters, their children, probably some of their friends show up too. Also my girlfriend and her father. Oh and peoples dogs show up, too. Like there's a milkbone trail to the house.
So all in all, it should be a fun time as usual!
