They didn't have other classes. And my co-teacher wanted me to prepare something "academic."
I'm cutting myself some slack because it was my first time doing summer camp and I had done as much research beforehand as I possibly could in the limited amount of time that I "discovered" I had. I had maybe two weeks to put together a workable program for the camp, and Charlie and the Chocolate Factory seemed as good a summer camp as any to do for the students.
Anyway, fool me once, shame on you. Fool me twice, shame on me.
