When I moved to Senegal in 2007 to work for a charity organization, the first thing I did was to hit Dakar, the capital. Not far from the city center, it also has one of Africa's biggest slums(贫民区)and its share of beggars. Street kids would tail me, begging. During a previous trip to Senegal, I was once cheated by a man. I'd wondered for years whether to give money to beggars in West Africa.

Near my apartment, I passed a group of young men in wheelchairs .Head down ,I walked by them quickly. As the months went by, I'd often come across them. I'd often see them at an outdoor basketball court near my office. They'd sit on the ground with their chairs upside down, tightening and adjusting wheels, waiting until the other guys left so they could play.

I'd stay and watch them warm up. They played with speed, rolling down the court as fast as I could run. A few weeks later I introduced myself to them with the help of Mafall, who was one of the guys .I started spending more time with them and eventually became something like an assistant coach.

The players quickly grew on me. I started referring to them as "my guys" to my colleagues. It was the most fun I'd had since I got to Dakar .Life on the street had made my players strong and they didn't back down easily. I was proud of them.
