MY GRANDMOTHER CAME BACK two years later. I was in middle school, and my pathetic puberty struck like a flash of lightning in the middle of the night — I suddenly saw all my surroundings for what they were: hideous and threatening. I had no friends, social life, interests, talents, breasts, straight teeth, likability, normal clothes, or charm, and every day I came home weighed down with dread. I started to fake illnesses so I could stay home with my 2-year-old brother. I followed him around everywhere, crawling when he crawled and walking on my knees when he learned to walk so that we were the same height.
