"The thing I was beginning to figure out about Sam and Grace, the thing about Sam not being able to function without her, was that that sort of love only worked when you were sure both people would always be around for each other. If one half of the equation left, or died, or was slightly less perfect in their love, it became the most tragic, pathetic story invented, laughable in its absurdity. Without Grace, Sam was a joke without a punch line."
