" Of course it hurt that we could never love each other in a physical way. We would have been far more happy if we had. But that was like the tides, the change of seasons--something immutable, an immovable destiny we could never alter. No matter how cleverly we might shelter it, our delicate friendship wasn't going to last forever. We were bound to reach a dead end. That was painfully clear. "
