This is quite a story, both engaging and sad. It must have been hard having a doppelganger so close and being intimidated by each other. It would have been nice if you could have been friends.

I know I have a doppleganger because I have been stopped more than once and spoken to as though the other person knows me well, referring to me by a different name, and I have never seen them before. I have never met my doppelganger though.
