Rainbow Punishments

In he car today, we were asking Aaron if he was good and did his work. He gave his usual vague, really avoiding the real subject way, and eventually we wound up talking about color cards. In his class, if you're good, you're on green. If you slip up, you're on yellow, if you slip up yet again, orange, and the worst, red. Aaron said,"If I was a teacher, I'd have first green,'cause the land and grass, then blue, like the ocean, then yellow, like a little fire, then orange like a big fire, the ones that are so hot you have to step away, then red, like a forest fire or when your house burns down. I don't think that he gets what the card system is really just based on what color you choose.
