Nerves.

I have to teach at co-op again tomorrow, so I'm having another attack of nerves. I don't think I'm the type for teaching a big group. I've been scrambling all day trying to plan enough activities to keep 20 kids occupied and learning about the great lakes states for an hour and a half. Whew. Last time I used all I had prepared including all the stuff for next time and all the emergency stuff. I hope it goes well.
