Story time was improv. Every night I'd sit down and wing it.
One night I decided to riff on the things kids don't know about grown-ups. For instance, that we play with their toys when the kids are in school. Sometimes we even let friends of ours play with their toys. The worse the behavior the more she laughed. If it's preposterous it's funny... but maybe it's actually true. That uncertainty makes it funnier. The tradition goes back to Struwehlpeter and to Belloc's Cautionary Tales, but these tales don't warn kids to behave. The idea is to warn kids about grownup behavior. The bias probably shifted to the child's side with Roald Dahl. Like I said, I hope I'm able to get this published before my kids are grownups themselves. They might not think it's as funny then.
