So Caleb comes up to me and says: "Mom come and help me with this money!"
I say okay and I walk into the kitchen where he has a piece of paper with drawings on it.
He exclaims: "See I'm making 100 dollar bills for everyone! Okay, now you draw the back of it.
In the middle here you draw a jail and on the side you write 100."
I ask:"why is a jail in the middle?"
He says:" Becuase on the real money there is a picture of a head on the front and a jail on the back."
"Oh, honey that is not a jail on the back." I reply.
"Oh. I thought it was a jail because that is where you go if you steal 'em."
Makes sense to me.
