Do you like games? Do you like playing games with children? Children have their own rules in playing games. They hardly need a referee(裁判) and hardly trouble to keep scores. They don't care much about who wins or loses, and it doesn't seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck so that their personal abilities can't be directly compared.
Grown-ups can hardly find children's games exciting, and they often feel puzzled at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone. He becomes a leader when it comes to his turn. He can be confident too. In some game, where it is his place to give orders, to pretend to be dead, to throw a ball actually at someone.
It appears to us that when children play a game, everyone knows the rules. More importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.
