A woman's ex-lover moves into her duplex apartment.

"I wanted to be with Mitch again the way we were after college, with that safety of the late-night sex call, the backup-plan date who was not really a date to parties filled with couples. But I did not have the courage to tell him that I wanted to pick up where we had left off before he married Janet any more than I could have told him I had loved him all those years ago. By the time he was free again (and moving into the duplex I owned), I had learned to seal off my heart from his casual, unofficial kind of love."
