'The experience of love has to begin outside of maturity; it's just that, if a relationship is to last, if love is to survive and develop over an extended period, we need to bring to the relationship a set of qualities quite different from those which took us into it in the first place. The Byronic hero might be madly exciting to have an affair with, would be a nightmare as a husband. Imagine Hamlet as a father. Imagine Cathy discussing mortgage repayments with Heathcliff. This is the internal tragedy of love. If love is successful, if our love is returned and develops into a relationship, the person we are must turn out to be other than the person we imagined them to be. Love craves closeness, and closeness always brings us face to face with something other than we expected. The person who looked so confident and full of life when we knew at first turns out, eventually, to have an array of hidden anxieties and fears.'
