Amicus Grief

Will brings the case against his friend Moby. Moby has constructed a "friendship and acquaintance theory" that helps her navigate the relationships in her life. She's entirely upfront about which people in her life are acquaintances, and which are friends. She says it helps her maintain better relationships. Will thinks Moby has gone overboard with the theory, and it's alienating her from other people. Who's right? Who's wrong?
