This is going to sound HORRIBLE, but I have to wonder... Do we all look alike?
To begin, and I am going to make this in all bold caps, THIS HAS NOTHING TO DO WITH RACE OR NATIONALITY AND IS NOT IN ANY WAY RACIALLY MOTIVATED!! PLEASE KEEP ALL THAT OUT OF THIS POST.
I have noticed that people of certain groups do look a lot alike. For instance, take my sister. She is the typical blond haired, fair skinned, blue eyed regular build woman. I and my mother have dark brown/black hair, we have tan skin and brown eyes. When we three go out some where, and we lose my sister in a crowed, we find that it is hard to pick her apart from other women similar to her. We will be running around looking for her, and we will see 10-20 other women who look exactly like her, and we wont notice it until we are right up on her. Not just the color of her hair and skin or build, but facial structures are the same. Which is what makes it almost harder to pan her out in a crowed of other women who look just like her. We have to do a double or triple take sometimes, as horrible as it seems lol!
But I notice that when I am looking for someone like me or my mom, its easier for me to find her in a crowed, than it is for my sister. She has a similar problem with us or anyone like us. So she even says that people that share similar likeness all look alike to her too. And being around a lot of other people, I have noticed they will say the same thing.
Which makes me wonder, as a curious kind of like a scientific stand point, do we only see differences in people who look like us? Like do blond haired, fair skinned people see the differences in each other more so than those of us who have dark hair and darkened skinned?
