"In an ideal world, marriage vows would be entirely rewritten. At the altar, a couple would speak thus: "We accept not to panic when, some years from now, what we are doing today will seem like the worst decision of our lives. Yet we promise not to look around, either, for we accept that there cannot be better options out there. Everyone is always impossible. We are a demented species." After the solemn repetition of the last sentence by the congregation, the couple would continue: "We will endeavor to be faithful. At the same time, we are certain that never being allowed to sleep with anyone else is one of the tragedies of existence. We apologize that our jealousies have made this peculiar but sound and non-negotiable restriction very necessary. We promise to make each other the sole repository of our regrets rather than distribute them through a life of sexual Don Juanism. We have surveyed the different options for unhappiness, and it is to each other we have chosen to bind ourselves."
