Hi Nuria! I say "Tall, White Man" as opposed to calling myself an "American". Let's say, a "non-Spaniard" or a "foreigner". I know there are many Spaniards who are tall and many who are very white, but still they most often have black hair whereas mine is light brown. I can imagine the older ladies turning to look behind them, at their eye-level, and they're looking into my chest. They look up up up and they see someone young-ish and totally foreign, probably wearing clothing that isn't absolutely typical for Spain, and smiling like someone who doesn't belong there. hehehee..

Saludos, MadridMan
