"Silly filly," Pinkie Pie said, pulling her into a hug. "Laughter wouldn't be so important if it were easy; you have to learn what makes others tick so you know how to make them happy as well as when to be serious so they know that they can always count on you and not dismiss you for being useless or insensitive. Laughter is a tough balance act, but the reward is having everypony smiling and happy and laughing with you."
