Already Knew That

Yesterday in science, we studied cartilaginous fish. First we talked about sharks; then we talked about rays, including stingrays. Suddenly Christopher piped up: "Nemo's teacher was a ray. He was their school bus, too."

How about that? Who knew? So I said, "Well, I guess you don't even need this lesson then, do you?"

"No," Christopher answered. "We already know all about rays."
