"Love isn't an act. It's a whole life. It's staying with her now because she needs you. It's knowing you and she will still care about each other when sex and daydreams, fights and futures - when all that's on the shelf and done with.
I'll tell you what love is: it's you at seventy-five and her at seventy-one, each of you listening for the other's step in the next room, each afraid that a sudden silence, a sudden cry, could mean a lifetime's talk is over."

Brian Moore

To keep going, keep breathing, when all you lived for all your life is not here anymore, is the tuffest task I can imagine. Isn't life without love but a silent sea shell?
