" At times I think of human relationships as something soft like sand or water, and by pouring them into particular vessels we give them shape. So a mother’s relationship with her daughter is poured into a vessel marked ‘mother and child’, and the relationship takes the contours of its container and is held inside there, for better or worse. Maybe some unhappy friends would have been perfectly contented as sisters, or married couples as parents and children, who knows. But what would it be like to form a relationship with no preordained shape of any kind? Just to pour the water out and let it fall. I suppose it would take no shape, and run off in all directions. "
