Two For the Seesaw

Years ago when I was a college theater student, one of the plays we performed was William Gibson's Two For the Seesaw. I saw it mentioned somewhere recently, and vaguely remembered that it had something to say about the nature of love and attachment. The library's battered copy hadn't been checked out in ten years, and a couple of pages were missing. The characterizations and dialog (written in 1958) are painfully outdated, but the theme, searching for a connection with the right person, is still contemporary.
