Me, too. I did the same thing with my college students, too, FWIW. (Teaching taught me more about parenting than any book about parenting that I ever read.

If you think about it, college students really have a whole lot in common with toddlers!)
Anyway, I have found that in general, people--adults and children alike--tend to rise (or sink!) to the level you expect of them. You can always drop back your language or define a word if someone's not getting it. But if you treat people like they have brains, they usually don't disappoint.
Within reason, of course...
