When John Adrain was in second grade, he answered a question wrong on a test, or so the teacher thought. The question was, do you have a fire engine?
Yes, he answered. And he was telling the truth. His dad collected military vehicles, so he got a note from home saying that his answer was in fact correct. A few weeks later, his teacher asked the class if anybody had a tank. She turned to Adrain and said, “does your father have a tank?”
