Do you believe there was someone in past who looked the same as you?

Yestarday I was listing some book with photographs of old families and portraits I found in library, and my friend suddanly said "Oh look, this girl in picture- it's you!" I was laughing, but when I looked closer, girl in picture was really very similar. I asked a few people for opinion, and they all agreed similarity is more then obvious. I allready made an attraction of this discovery, untill moody librarian destroyed my fascination, saying: "Oh please, all old portraits look similar, and you darling have the same hollow look they do, so, stop disturbing these people who're studying, and go accuse Botticelli for copyright or whatever." :)
