Skinny is not synonymous with confident. Nor is funny synonymous with happy. But if you weigh 110 pounds, and make people laugh they will ignore your tear stained cheeks. They will overlook the limpness of your movements.
You could fall dead without having been known by anyone. They will peer at your corpse and claim to have known you. They may even cry.
Had I been fat and humorless they would have known me.
