So birds do this thing where they swoop in front of a car and catch the windstream around it and it feels pretty mocking. Well anyway, I was out on my bike once and this bird-looking fucker flew up alongside me, right? He goes to swoop in front of me and you can just see them fall about an inch before flapping off. They thought I was a car! Whose the real mocker now? Probably the bird- I still can't fly!
I imagine, in the event no one ever knew, found out, or cared about the swap, then life would go on, just a bit more weird than before. I can't imagine it in a modern society, even briefly. We have too many records of too many things. And beyond that, it'd depend on stuff like who they are and how long it's been. Maybe on how readily both of them can convince people that they are mentally sound and worthy of respect. Who knows? That'd be wild.
Unrelated, but I think the fair folk used to swap infants out with ugly versions, or dying versions? Am I mixing up fairies and the UNSC again?
To be fair, I've never talked to anyone whose been properly shot in the heart and didn't go on to quickly find love. Makes you think..
