Seriously, they are.
Not only do they have warts, topical skin conditions, various physical tics, and other minor abnormalities, but their thought processes are different. They see things you don’t see. They hear things you don’t hear.
They think things you don’t think.
If its a physical thing, you might be in luck. Remember that kid in your class with the deformed ear, or the unsightly mole, or crooked teeth? Childhood is the great era of corrective surgery, braces, and the lasering away of unsightly blemishes. They’ve had that shit taken care – because doing so helps them blend in and walk among us with their weird, mutant thoughts.
It might be your world, but they’re adapting to it. And soon it’ll no longer be your world.
It will be theirs.
