On the first day，the boy 3 some nails into the wall. The next day，he put4 fewer nails. A few days later，he found it's not 5 to get angry. After a while，the boy was happy every day. Then his father asked him to 6 nail each day if he didn't get angry. After some time，all the7 were gone.
Then the father took the boy to the wall and said，"Well done，son. But，look，the wall is full8 holes. It will usually be the same. When you say things in anger，you leave scars（伤痕） in people's hearts. No matter how many times you say9 ，the scars will always be there. "
