The children in our neighborhood ran around as most children do during play, and Joey would lump fight m and run and play, too. In seventh grade he decided to go out for the cross-country team Every day he trained with the team. He worked harder and run more than any of the others. Although the entire team runs only the top seven runners have the potential to score points for the school. We didn’t tell him he probably would never make the team. so he didn’t know.

He continued to run four to tire miles a day, every day — even the day he had a 103-degree fever. I was worried, so I went to look for him after school. I found him running all alone. He had two more miles to go. The sweat ran down his face and his eyes were glassy from his fever. Yet he looked straight ahead and kept running.
