The teacher asked the little girl if she was going to the Maypole dance.
"No, I ain't going," was the reply.
The teacher corrected the child:
"You must not say, 'I ain't going,' you must say, 'I am not going.'" And she added to impress the point: "I am not going. He is not going. We are not going. You are not going. They are not going. Now, dear, can you say all that?"
