The sad thing is, if we did get to know each other, we'd find out we have a lot more in common than we think. We're different, sure, but mostly it's a difference of style, not substance.

Sometimes it seems like it's a problem we'll never solve. Bringing black and white people together is important for common-sense reasons. The more types of people we know, the sharper we'll be.
