This happened to me once, too, but it was such a sad, uncomfortable situation that I felt I needed to stay put. I was doing a birthday party for a boy in Kentucky. His entire class had been invited, and NOBODY showed up. This kid's mother and I were both hopeful that if I waited long enough to start my show, somebody would arrive, but it was not meant to be. Fortunately, there were some aunts and uncles there, so at least there were some adult guests. Nevertheless, I felt terrible for this boy, and I didn't mind hanging around a bit longer. We actually ended up having a pretty good time.
