How could I possibly be so upbeat when my surroundings were so obviously heavy? I was two. Age is no excuse. I feel tremendous guilt every time we rewatch the home video. How could I not have known better? What a stupid idiot. How could I have not sensed what Mom needed? That she needed all of us to be serious, to be taking the situation as hard as we possibly could, to be devastated. She needed us to be nothing without her.
