There are times I look middle eastern. I have dark skin that tans easily and depending on how my eyebrows are shaped, I tend to get a lot of "are you Egyptian" "are you Iranian" "are you Jordan". When I was living in NJ, one of the only two states in the US that mandates gas attendants pump your gas, I asked one of the men, after asking me if I was middle eastern, why he thought so. He said it was my eyes. Others have since said it too.
Growing up I heard my older relatives say "she has such big brown eyes" and later on my godfather said "brown eyes tell emotion".
I don't really see it. Eyes are eyes...but I guess I got a good set, even if I am nearing legally blind.
