that's why I never had big parties at my house...that right there. Whenever my folks left, I had my closest friends and maybe a few others that I knew well enough over...I think I've had maybe 10 people at the most over at any given time. Wifey and I housesat once and had some people over, since my folks have a pool table, hot tub and all that good stuff, but we kept it very contained and it was people (and their signifigant others) we knew and my family had known through me growing up.
At my own house, I've had maybe 8 or 9 people at the most...the exceptions would be birthday parties for my daughter, but again, we don't throw stupid bashes like a lot of parents like to do...you know, invite 100 of their own friends over when it's not THEIR birthday, it's their kids' birthday. 100 adults and like 3 kids total. You know what I'm talking about.
