A common conversation with Isaac goes like this:
"Mama, have you ever wondered why a four looks like a four?"
"Well, someone decided that a four needed to look like that I guess."
"Oh. Was it the same person who made airplanes loud and said we always have to have fruit or vegetable with lunch?"
Or something like this:
"What is it?"
"Did you know that if you just sit on top of the seat and you don't hold on then you will just go ZOOM and ZOOM and back and up?"
"Yeah, and you will spill you soda and beer. So you better be careful."
He's right. I better be careful.
