Many years ago, I read a book where the main character, a war veteran relearning to walk with prosthetics, once took heat from a train passenger for not giving up his seat to another veteran, who was “visibly wounded.” At first, the guy was outraged by this injustice, but then he realized that this case actually meant he had effectively learned to walk again!
The hero of our story today, the user u/SnarkyLostLoser, is a disabled middle-aged man, and he recently also took heat on a bus for not giving up his seat. However, the author had every right not to stand up, and this situation left him with nothing but sadness.
