This happened to my son recently, getting his passport photos taken, the girl in the store, said to him don't you remember me, he goes uh no, you know from fraser high, he went to boys high, and then she called him Jacob, another case of mistaken identity, she said you look so like him, like his twin, mind you my son has a half brother somewhere , who knows where he is., but his name is cole, but he often gets told he has a twin.
