“I can’t have ADHD. I can sit still for a very long time.”
Literally my parents. And teachers. I was “such a quiet kid” who did well in school. Never mind the fact that I would chatter to my parents and brother to the point where they’d actually get rather upset with me interrupting everything.
Turns out I excelled on tests solely because it was quiet. The doodling and daydreaming I did managed to keep just enough information flowing into my brain that when it came to tests, I just worked through them like puzzles.
I remember classes after I started taking Ritalin in highschool. Holy crap. I actually remembered learning. It was incredible. I didn’t have to figure out things on my own. Tests were even easier because I had the answers beforehand.
