Quote from Sally in Lonely Dick
Dick: When humans come together, they connect somehow. And when one of them goes away, they pull out a part of you. Dr. Albright took a piece of me with her when she left. And when she came back, I felt normal again. Well, as normal as one can feel in these bodies. Sally: While we're on the subject of bodies, why is mine so much higher maintenance than yours? Tommy: I think the economy relies on it.
