Glad That's Behind Me

I gave The Ethan Allen Connection presentation for the first time yesterday. The audience was 160 sixth graders. That was a little older group than I usually speak to and quite a bit larger. They were so mannerly I was afraid they'd all dozed off from boredom. Usually I have kids raising their hands and wanting to ask questions or offer comments during the talk. Yesterday there was none of that. Zip. Nada.

Maybe the problem is mine. Why do I assume something is wrong if people are being polite?
