(At Marial's wedding, Peter and Catherine have little speeches...)
Peter: If I may, I would like to wish the couple well. And maybe add a few words on marriage. I understood little about marriage until I met my wife. Now I know it to be a lot like the roller coaster she herself built, ups and downs, exhilaration, a... a slightly terrifying sense that all will go awry and everyone will die. But in the end you stay on the rails... kept there by gravity and the force of your love.
Catherine: My advice to you is to expect the unexpected. Marriage is both a joy and a place where you will be dealt unbearable griefs.
Peter: If love is strong enough, all griefs are bearable.
