From the Interview:
KW: I know you’re a member of AKA, the pink-and-green sorority. Are you still in touch with any of your sorority sisters?
WS: The ones I went to school with at Hampton, we still keep in touch. It’s just so hard getting together, because we’re scattered all over the country. But when I’m on tour, if someone is in that city, she’ll come out to the show and it’s always great seeing them.
