What to Be For Halloween

This morning, I asked Rollie what he was going to be for Halloween.

"Spider Man," he replied.

"Tiller, what are you going to be?" I said.

"Bida Mon." [Spider Man. She mimics everything Rollie does.]

I said, "Well, what am I going to be?"

Rollie didn't even look up, but stated very decisively, "A cow."

Um, thanks.
