Small Grown Up

I was listening to my 5 and 6 year old boys play. Since I've read Dr. Seuss I've always just called them little boy 1 and little boy 2. Annnnyyywayyy....The conversation went like this:

Little boy 2(5 years old): No, you can do that. You have to have a grown up to do that. Here, let me do it.

Little boy 1 (6 years old): Your not a grownup.

Little boy 2: I'm a small grownup.

Well, that explains it all!
