My 10-year-old son got kicked in the shin yesterday. He was very excited. His friend said you know a girl likes you if she kicks you. The friend was kicked by a girl a couple days earlier. So when my son's crush kicked him yesterday, he said, "I'm in love." Moments later, the same girl kicked some other kid in the nuts. My son was jealous. And outraged. "That two-timer!" he shouted.
