There's a phenomena that she's stumbled onto that I hadn't recognized at my days at ISU. My daughter has become a little United Nations, of sorts. Her best friend on campus is Puerto Rican. Her other closest friends are African American, Chinese, and Ecuadorian. My little girl is pasty white, and I couldn't be more proud of her. But what she noticed is that the kids from Iowa tend to be friends with the kids from Iowa, the kids from Minnesota tend to be friends with kids from Minnesota, and the kids from Chicago tend to be friends with the kids from Chicago... with few exceptions. She said, "dad, there's honestly just not enough kids from Texas here apparently; at least based on the way the social groups form". But her African American friend is, in fact, from Dallas and the two of them are close and have decided to rent a townhouse together next year.
