A tricky social situation I’d never thought of: what do you do when your identical twin dies?
Well, you bury and mourn him or her, of course, and then go through their stuff. (You know it will fit you!) But here’s what I’m getting at: when you show up at the funeral, many of the deceased’s friends, co-workers, etc. will never have met you. I’d guess that somewhere around a third of them might not even know he or she was a twin.
In other words: there will be whispers, pointing, dropped drinks, maybe screams. You will be widely assumed to be the dead, come back to life.
