One of my most favorite things that ever happened to me in school was when I was in 4th grade. Everyone took a math test and the teacher said only one person passed and that person got a perfect 100. everyone else is going to have to retake the test you all failed all except for that one person. So they were like who did it who did it? They started guessing like the smartest kids in class and she kept saying nope nope nope. And then finally after almost every single person in the class has been named except for maybe me and 6 other people she said my name. And at the time there was actually a girl whose name was extremely close to mine like one letter off and it sounded very similar. So everybody was like do you mean her. And the teacher said no I mean and then said my name again. I was both like shock that I actually made a perfect grade that even the smartest kids in class failed but I'm also pissed that everybody was like oh there's no way she's smart enough to get a perfect score.

Maybe a sign that the teacher sucks at there job?
