I Vanish

Many times a kid trying to tattle will come up to me and say, "Mr. Bowers, he was doing..." and when they get to the word "he" they turn away from me and point to the other kid across the room and I never hear the rest of what "he" did. I will ask them to tell me again, and the same thing happens! I never get to find out what the other kid did. Finally, I came up with a solution to this problem:

As soon as the kid turns away from me to point, I will sneak off and hide. Then I will watch the look on the kids face as he turns back around and discovers that Mr. Bowers has disappeared!
