Because I didn't have any. Little Jimmy had some and he's alright. ,F: Of course, we sat in the sun for a long time, but I suppose it couldn't have been the sun. ,M: That's true.

I thought you have. ,M: Jennie, I didn't wash them. I was sure you did. It must have been the apples then. Oh, I feel worse now. Let's go see a doctor.
