I saw a little girl in a store once who looked a lot like my sister, Kate, did at age five.  Without even thinking about it, I  patted her on the top of her head and said: “Hi, Katie!”.  I nearly yelled when she turned around and wasn’t my sister.  To make things even weirder, my sister hadn’t been five in quite some time, say, ten years!  The little girl was perfectly fine with the case of mistaken identity.  Her mother, on the other hand, looked at me rather askance, especially when I tried to explain that I’d mistaken her daughter for my little sister who was now fifteen!
