Well! I'm glad we clarified that before he was asked to demonstrate in school!
A few days ago, Ethan and I were talking about fire. I don't remember how it came up, but I casually mentioned to him the "stop, drop, and roll" technique. He listened, nodded, and we changed the subject.
Just tonight he was playing around, being silly, and pretending like he was on fire. So I used it as an opportunity to show me what you do if you really ARE on fire. He forgot, so I reminded him "stop, drop, and roll".
He stopped in his tracks, promptly DROPPED...his pants...and rolled.
