A Messy Situation

I just got out of the shower and heard Michael yelling to me, "Mom, Preppy had a really messy nose, and now it's all gone!"  He said, "It was a really, really big booger."  I came down and said, "where did he wipe it at?" Thinking that it was smeared somewhere, but Michael said, "I just got it all gone in the paper towel (he meant toilet paper)."  I said, "Thank you Michael, you are such a good boy."  His response, "Yeah Mom, I'm really, really good at picking boogers."
