We may dig in our heels and dare life never to change, but, all the same, it changes under our feet like sand under the feet of a sea gazer as the tide runs out. Life is forever undermining us. Life is forever washing away our castles, reminding us that they were, after all, only sand and sea water.

Erica Jong (b. 1942) American writer, poet

Parachutes and Kisses (1984)
