对那些在一个连最自发的绳球比赛都要精确记分的体育时代里长大的人来说，不记分的比赛显得完全是激进的。
For those who grew up in a PE era when even the most spontaneous match of tetherball was scrupulously tallied scoreless play seems downright radical.
我们中的一些人在操场上跑步，或跳过一些跳过绳，打羽毛球，踢毽子，读了几本书和其他人围坐在和别人谈天的不幸。
Some of us run or jump in the playground, some skip ropes, play badminton, kick shuttlecock, read some books and the others sit around and chat with each other cheerfully.
