:: Iranians mostly are medium dark skin colour, with brown eyes and brown hair, but at the same time there is a variety of physical appreance, like green/blue eyes, blonde/red hair, very bright skin (moonlightish), tall, short, hairy, bald, bushy eyebrows, big noses, acceding small noses and et cetera. With this variety of looks, when you as an Iranian live in abroad it is not easy to recognize another Iranian specially when they are not speaking (no matter what language), but as soon as they catch each other eye to eye, that's it, voilà! An exchange of smile, or nod of heads shouts "Hi you fellow Iranian,...". And how they do that? I don't know exactly, It's all in that wireless eye to eye connection. The look at people's eyes all the time, friends' eyes , family's, even strangers'.
