| My 8-year-old son, Kevin, has made friends with some boys in the neighborhood. He has been 1 with them after school. My wife,Qugen, and I are _2_ he has other kids to be with and we have_3_ and encouraged him to play with his friends. We also want Kevin to learn _4_,so we have asked him to tell us 5 _ he's going and to come home at a specified time. The 6 started when Kevin didn't come home on time. On one occasion,I asked Kevin to be back at 6 pm. By 6:30,I needed to go 7 him. I found him at a friend's house,and he looked _8_ that he couldn't continue playing. After we came home,I sat Kevin down for a talk about the 9 of keeping his word. I told him I was not worried about him arriving a few _10_ late,but after half an hour,I'm going to be 11 . He told me he understood. The next day,I came home from work at about 6:30 p.m. and Qugen asked me to go and get Kevin _12_ she said he should be bac  k home at 6. I walked to his friend's house and a look of _13_ appeared on Kevin's face when he came to the door.At 14 ,Qugen and I spoke to Kevin about why he didn't come home on time again. He said he just wanted to _15_ playing. This was 16 ,so Qugen and I decided to ground (罚不准出门) him for a week. This 17 no playing with his friends. For the next week,whenever his friends came to ask for Kevin,we let him _18_ to them that he was grounded. We felt this would help him be responsible for his 19 . As a 20 , I believe one of the most important things we can teach our kids is self-responsibility and that actions have consequences. | ||||
