I was personally acquainted with the paddle from the first grade on. When I was in the fourth grade, I was walking down the hall during class and when I passed the sixth grade room, I saw a girl giving herself swats with a paddle like this one.
I was mesmerized. The teacher was supervising and the whole class was watching. I froze and watched until I felt I would be caught the next second.
Who she was or what she did I never found out.
