Marriage

"Why do people get married?" he asked.

"It's not passion," she answered. "It's because we need a witness to our lives. There's a billion people in the planet and, I mean, what does one life really mean? But in a marriage, you're promising to care about everything-- the good things, the bad things, the terrible things, the mundane things... all of it, all the time, everyday. You're saying your life will not go unnoticed, because I will notice it; your life will not go unwitnessed, because I will be your witness."

~Susan Sarandon in "Shall We Dance"
