Immaturity: A teacher's greatest weapon (according to at least one student)

On the last day of the school year, I receive a lot of cards and letters from students expressing beautiful and hilarious and occasionally insightful messages to me.

This year I received a card from a student that said this:

“I think the reason you’re such a great teacher is that you are basically the child version of yourself. You grew up and got old, but not all the way. You’re like a big, responsible. smart kid. So you still know what it’s like to be a kid.”

I would like to think that I am an effective teacher for reasons that go beyond my possible immaturity, but rarely has someone said something about me (or about the teaching profession) that has rung so true.
