Me - Aren't these grapes nice and crispy?
Joy - No, they taste like soap.
Me - Soap? Maybe your mouth tastes like soap.
Joy - No, my lunch didn't taste like soap. Maybe I am allergic to grapes.
Me - Hmm.
Joy - Did I used to be such a great reader before I had grapes?
Me - Um, no. You had grapes long before you were such a great reader.
Joy - That must be it. I must be allergic. Grapes make you change. That must be why I am such a great reader.
