Know when to call it quits. A party can be raring for hours, but you have to know when to start suggesting people head for the exits. If it's 2 AM and you have to clean up a pile of red Solo cups the Egyptians would be proud of, don't feel embarrassed to start rounding them up like cattle. It's been fun, it's been real, but party time is over, folks. It's time to call it a day. •An easy way to do this is to start cleaning up. People will generally get the hint -- and hopefully they'll help out! Tell them you're very glad they came and you'll see them soon -- the next party should be on their turf! You'll bring your famous enchiladas.
