My son, Avery, is the color of caramel. He is 15 years old, stands nearly 6 feet 2 inches tall and weighs almost 200 pounds. He is a Big. Black. Boy. Because Avery is a big black boy, when we moved a couple of years ago, one of my first tasks was to parade him around our new neighborhood. Smile and wave, I told him, so they know you belong here.
