Dear dude at the store last night,
I’m very sorry that you were injured when you bumped your leg on my wheelchair. When it was standing still. And you looked right at me and walked into me. Your mumbled response should have been enough to clue me in that you were actual royalty and I should have thrown myself out of my assistive device at your poor, mangled feet, and kissed them and begged forgiveness for existing in this store, which is clearly for Able Bodies Only. I do hope that you don’t have horrific, trauma-induced nightmares about me. I am very threatening, I agree, especially to someone such as yourself. All 5 feet of me could have, at any moment, mutated into a thousand tiny wheelchairs for you to bump your legs on! The horror! 

Please accept my deepest condolences on the loss of your dignity when you yelled “DID YOU SEE THAT? SHE HIT ME AND TOOK OFF!” as you walked away. I mean, I’m sure you do that to every single other person you purposefully walk into in public, so it’s probably no big deal.
