TL;DR: I got teased for being skinny and lean in elementary, absolutely demolished the teasers in a swim test 25 at a YMCA camp, and they never teased me again after that.
Back in 5th grade, we stayed one night at a YMCA camp (Sherman Lake, Michigan). To go boating, we had to pass a swim test—25m without stopping. As a skinny kid, I got teased a lot, but I’d been swimming competitively since age 7. When it was my turn, I went bare-chested and got laughed at for being small.
But once in the water, I swam the fastest time, beating the teaser next to me while going 70% effort. The teasing stopped after that, and I learned to never underestimate what you don’t see.
I was a synchronized swimmer who beat a club swimmer that bullied us. I shattered her record at champs, and everyone celebrated. She had a meltdown and didn’t say a word. Great day for nobodies!
