It's not necessary, but it might help if you read part 1.
Sick with children, the colossal red-brick building sneezed and the entire fourth grade shot out of its doors. 122 ten-year olds exploded onto the green hillside, kicking dust and mud onto the beastly edifice. They were like a happy load of buckshot, a swarm of jubilant disorder, all of them running, tripping, jumping for freedom. All of them except for one; a really little, skinny one called Adam. This one shuffled from the building, his frail, brainy body moving in slow motion while the other children blurred past. He stared at the grass as shoe-drawn currents ripped through it, fatefully tearing and snapping select blades, leaving others to stand the test of life for at least a few more moments.
Adam shrank into the grass, got small like the ants and climbed aboard a prime leaf, the perfect launchpad. He waited and watched, ready to surf the next hapless wave that followed in the wake of his new classmates.
"Heads up! Heads up! Heads up, uh, Adam? Heads up ADAM?" He looked up, but it was too late. Whack! A kickball to the side of the face and Adam dropped to the ground. Tommy Keeler, a miniature lumberjack with hair the color of vacuum-cleaner dust, ran over and grabbed the ball. Adam held his burning right cheek and hid his pain, keeping Tommy Keeler in his periphery, afraid to look him in the eye. Third-grade legend taught Adam that to look Tommy Keeler in the eyes in a time of weakness meant certain death, or at least a wedgie.
