It’s great when the turnout is more than you expect and more than you’re ready for. People are flexible, even helpful. They grab extra chairs and squeeze in next to strangers. Some of them even sit on the floor. There’s an energy born of good will and anticipation that makes it work.
You go with it, tweaking your program to suit this larger-than-you-were-ready-for crowd. It works.
Now you know. Next time be ready. You can’t ask for patience and flexibility over and over again and keep getting it. Adjust. Season to taste. Enjoy.
