Laura I am a 25 year old multiracial woman. I'm not quite sure what races there are in my background, since my father is multiracial too. He looks like a light-skinned black but he's from Central America, and it's pretty obvious there's other stuff in his background. My mother is white. I look white but like there's "something" else, but most people don't guess what. I have slightly tan or sort of golden skin, dark brown, curly hair and my eyes are a dark green and brown hazel mix. I've been asked if I was Greek, Jewish or Arabic before. I guess it doesn't bother me too much. I'd rather people be curious and honest and ask than just pretend to know what I am. I've also been able to educate people who maybe weren't sure if a multiracial person would be "normal" (no, we'd be schizophrenic!). I have a biological sister who looks a lot like me, with the same skin tone, curly hair and hazel eyes. I also have an adopted brother who's half black, half white, and it's pretty obvious that his biological father was a lot darker than my father is. People who see him assume he's black, and people who see me assume I'm white. I think he has a harder time with racial identity, since our society is biased towards white.
I grew up in an almost totally white town and therefore I mostly identify with "white" culture (whatever that is) as opposed to identifying with "black" culture. My parents really didn't do much as far as talking to us about race and identity. Most of the time as a kid I didn't think about it, and the biggest conundrum was filling out the info forms each year at school where they asked you what your race was. It didn't occur to me until probably about college that I'm actually part Hispanic, not just part black.
Still, race isn't a day-to-day issue for me, and I recognize that part of the reason for this is that I "pass" as white. This isn't something I try to do, but it just happens, but it means I don't necessarily deal with the subtle racism in our society the same way that, say, my brother does.
