When I was a kid and teenager there were a couple of people who somehow managed to get broken or sprained bones over and over and over again. Some of them really seemed to like the attention associated with it and would make sure they got into school even when they could’ve taken loads of days off
People even do this into adult life! What are they doing that leads to so many injuries??
I’m glad my “character design” is just that scar, though. My prescription glasses were scratched when this happened — without them I’d need to change my class from rogue to pirate! (I also got a small scar just above the lip, from the same event. But it’s usually hidden by the beard.)
Gotta agree with [deleted], it’s all about making some story up. Let’s say you fought a jaguar in the wild! (Or a cat if you want something more believable.)
