Get off the bus. Walk home. Eat a snack. Walk the dog. Do homework. Every day was the same. As Jimmy was walking Socks for the third time in a single day, just to get out of the house, he thought about ways he could make his life a bit more interesting. Not that he wanted too much excitement. Kelly, a girl in his world history class, was a competitive swimmer. And not just for their school. She swam with a club in town and trained every morning for two hours before school and again for two hours after. That seemed like too much to Jimmy.
