" You've found a way to stay sane, Renfew--even if that means admitting a tiny piece of piano-playing madness into your world. But there's a cost to that sanity, and it isn't moi. the cost is you can't ever allow yourself an instant of hope, because hope is something that will always be crushed, crushed utterly, and in the crushing of hope you will be weakened forever, just as surely as if you'd mainlined some slow-acting poison."
