Corbin says

Yesterday Corbin went with me to the grocery store. We had the windows down, and the kids tunes turned up. Corbin says "mom, why are the planes pooping?" To which I said "ummmm.... What do you mean?" He says "look up there, in the sky! The planes are pooping!" So I look up and there are a couple of planes off in the distance. Behind them are white trails in the sky. I guess because it is coming out of the back end of the plane, naturally it must be poop. "It sure does look like they are pooping, doesn't it?" I said. "Yup, I guess that's what clouds are mom! Plane poop."
