My parents signed me up for Big Sister, Little Sister, and I picked Kim as my mentor. Dean: What? Wait, my sister? Why would you do that? Keisa: I don't know. Whenever I saw your sister with you, she always seemed so cool. Adult Dean: Keisa thought Kim was cool? Maybe she wasn't as smart as I always thought.
