guests who just won't leave
I couldn't find a thread on this topic, so here goes...
I had a Halloween party once that was still going strong (but I wasn't) at 3:00 A.M. so I put on Nick Cave's "Your Funeral, My Trial" (which is very dirge-like) and everyone cleared out within 15 minutes.
So, my advice to get rid of guests who won't leave is to change the mood with music and lighting. If things are lively, put on something slow and vice versa. If the lights are low, brighten it up.
No offense to anyone, but rap and mainstream 70's and 80's music will drive me away every time!
