The most interesting story I ever ran into from a stranger was at the DMV. I was talking to a man that had been declared legally dead. The process of coming back from that was long and arduous.
He got his life back together, everything right with the government agencies through an extensive investment of time.
Two years went by, and a clerk in a government agency noted that some one that had been declared dead was in the system as alive, the clerk decided to correct this issue.
The clerk's work resulted in him being declared dead all over again, and needing to completely repeat an extended process all over again to prove he was alive.
