movies and bawdy comedies. They love snowball fights, skateboards, birthday parties, and action sports. They love laughter and thrills, challenge and daring-do. They want to leap off thirty-foot cliffs into murky water below. They want to go on zip-lines, amusement-park rides, and water slides. They want to score the winning goal, hang out with their crazy friends, and eat pizza seven nights a week. They spend their waking moments thinking about, pursuing, or engaging in their desires. And then they walk into your classroom.
