Kusa, a 10-year-old boy, has looked out for his big sister, 12-year-old Pahnuly, for as long as he can remember. At school, he helps her unpack her things at her locker. At home, they read together, play games and practice counting.

Pahnuly has autism (自闭症). People with autism often have trouble talking with others. They might repeat things over and over, or be interested in only one subject. But it was Pahnuly that inspired Kusa to think differently. One day, they played ping-pong with their parents at home in Brooklyn Park. But Pahnuly struggled with it. So Kusa wanted to find a way to make it more suited to his sister’s needs. He came up with a new game based on ping-pong. It is called Aeropong because the ball seems to float in the air. In Aeropong, a ping-pong ball hangs from a frame. The players hit the ball back and forth. It’s kind of like tennis, but no one has to chase the ball.

At first, Pahnuly didn’t show much interest. But soon, Kusa heard a sound coming from the front room. Clack(吧嗒声). Clack. Clack. Pahnuly had picked up a paddle (乒乓球拍) and was tapping the ball. Then, she started hitting it back and forth with Kusa and their dad. Eventually, the family took a trip to Menards to buy some PVC pipes and fashioned a portable frame for the ball to hang from. They also designed rules and ways to score points.

Word spread at school about Kusa’s game. His teacher, Stasica, asked him to tell his class about Aeropong. Kusa was usually shy, but when he talked about his game, his face lit up with excitement, Stasica said. Kusa told his classmates the game was meant to make people smile, especially his big sister. "When she scores," he said, "she dances."
