" What I dread is the moment when her understanding turns to compassion, and her tenderness, her concern, come dangerously close to pity and maternal solicitude as to change the very nature of our lovemaking. 'No, no, my darling, we mustn’t, you will strain yourself...' Of course I should have spoken to her frankly, from the first. But to name the Devil is to conjure him up. And the moods of lover are contagious. There is that hazardous balance between them where the misery of the one brings on the insecurity and anxiety of the other; things quickly go from bad to worse, until they can no longer speak about it and the silence grows like a wall between them. "
