I've heard of mistaken identity but this is ridiculous!

A young surf board maker from New Zealand was told to give me a lift to work in his combi van, I worked in the surf shop below the flat he was staying in. I was a bit disconcerted by the way he kept staring at me and later, when I was in the communal kitchen making tea, he put his head round the door and said he had something to show me! He was holding a photograph album and as I opened it (rather nervously) I was shocked to find photographs of me! I asked indignantly where he got them from.....though, as I looked at them, I did not recognise where they had been taken. He laughed and apologised and then said 'That's not you.....those are pictures of my ex-wife'. I was stunned - I have mistaken people for someone else and even been mistaken for someone else but I had actually mistaken someone else for myself. I guess this is really his coincidence, not mine. He had travelled all the way to the UK to get over his divorce and his first job was to pick up someone who turned out to be his wife's double. Poor guy.
