They Made It All Up
My mom was a language teacher at my high school, and years after I had graduated, she called me kind of upset because a group of guys was trying to make her look dumb. The class was supposed to write one of those team dialogues in Spanish. They had a week or so to prepare it, then they had to perform it in front of the class.
When she called on them to do theirs, they said: “But we already did ours, we’re not doing it again.” She said, “You definitely didn’t do it, I don’t have any record of it here and I would remember it if you had.” They simply refused to do it, insisting they already performed it and that it was her fault she didn’t take notes or put their scores down.
She was in the middle of questioning herself when one of the good kids came and told her the truth. They hadn’t really done it, and they had just been bragging about making her look stupid. They apparently even threatened the class if they said anything. Well, obviously my mom was appalled, but she came up with an amazing revenge plot.
My mom was really into yoga at the time and got a great idea while meditating. She went in the next day and said, “Boys, I owe you an apology. I found my notes on your presentation and I do remember it, I don’t know how I forgot!” She then went on to describe all the grammatical mistakes they made, all their word choice flaws, everything. All made up. She failed them all on the project, and they couldn’t do a thing about it without admitting they’d made it all up.
