"Malcolm listened to her laughter, and for the first time in his life he knew that everything was going to be all right. Niceness, he realized, it was not enough, and Love was only part of the rest. You had to have laughter, too. Laughter would make everything come out right in the end, or if it didn’t nobody would notice."
