7. Mother and Son

A: Son, come here please.

B: What is it, mother?

A: Did you touch this frosting after I told you not to?

B: No, I didn't touch the frosting.

A: Then tell me, why is it all over your face?

B: I ate some, but I didn't touch it.

A: You should not tell lies!

B: I am not lying. My hands did not go near the frosting.

A: Then how did you eat it?

B: I used a spoon, so I didn't touch it. I didn't disobey you.

A: You knew what I meant. No dessert for you tonight.

B: That's alright. I've already had some frosting.
