Diversity and Racial Reconciliation

In high school, my friends were a "rainbow," as my mom put it one day. My best friends were Indian, the artist in our group was Mexican, the druggie (though I didn't know he was into that stuff at the time) was half Japanese, the unique Alison was Asian, the guy who asked me out every day for three months in a row was Native American.... You get the idea. I'm slightly depressed now, not only are all those friends gone, but all my friends now are white. There's a girl I know who is black (I never quite know how to classify them, my neighbor couldn't be called African-American as he was neither, being from England), Cody looks to be at least half-Asian, Juan is Latino, I think. They're all pretty cool, but I'm not close to any of them. It kind of sucks. How many people at APU are white, anyway??! I miss the "rainbow" I had back home, where everyone's differences were acknowledged and even celebrated. Here, I get the impression that it would be rude even to mention it...?
