I've thought of an example to be added to the Impossibly Mundane Explanation page, but I don't know the name of the story. It was a science-fiction short story. A woman sees two men who look alike, one of whom is trying to avoid the other. She immediately realizes that he must be a time-traveller, because the other explanation — that they're simply a pair of identical twins — seems unlikely. I don't remember any other details of the story.
