I have a fairly unusual first name (Merrick).
One day I was stood talking to a friend at the fruit and veg. stall he runs when another guy came over to say hello to him.
After a brief conversation the other chap left and I asked who he was, "Oh he's called Merrick" said my friend.
When I asked why he hadn't introduced us as we both shared this unusual name, he replied that he didn't think it WAS unusual.......well HE knew TWO of them.........
