In the 1970s, when I was very young (I’m thinking eight years old), my school arranged for everyone in my grade to attend swimming lessons at the local pool once a week. I wasn’t a particularly good swimmer, but I listened carefully to the instructor, did my best, and had fun.
The lessons came to an end, and the instructor informed us that we’d all passed and could therefore take the more advanced class next time. We were all proud and happy (plus we got cloth badges we could show off to our friends and families, which was kind of cool).
As I was about to leave the pool area to shower and get changed, the instructor called my name. I turned, smiling, thinking she was going to say something nice like “Good luck in the next class.”
Instead, she leaned down and said:
Instructor: “You were the worst swimmer of the bunch. I was going to fail you, but I changed my mind, because I wanted to have a full class of passing students.”
I could feel my face fall. She nodded at me, evidently satisfied, and went back to what she’d been doing.
I don’t know why she told me that. If her goal was “crush a little kid’s spirit and make her cry”, mission accomplished.
