This is mostly for me, but worth looking at if you've got a minute.
I've had the link to this article in my email for almost a year now, since Tom GodKing stumbled across it, and I keep forgetting to share it. It's a good post, but really it's just the comparison of children to stoned adults that gives me the giggles.
"If you’re having trouble figuring out how to deal with a child in a game, try thinking of him as a stoned adult. It’s not polite to draw attention to his being stoned, so just explain patiently and expect some weird lapses of judgment and the occasional flash of surprising insight."
