Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That’s every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”

My 8yearold son,Kevin,has made friends with some boys in the neighborhood. He has been 36 with them after school. My wife,and I are 37 he has other kids to be with and we have __38__ and encouraged him to play with his friends. We also want Kevin to learn __39__,so we have asked him to tell us __40__ he's going and to come home at a specified time.
The __41__ 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 __42__ him. I found him at a friend's house,and he looked 43 that he couldn't continue playing. After we came home,I sat Kevin down for a talk about the _44 _ of keeping his word. I told him I was not worried about his arriving a few __45__ late, after a half hour, he told me he understood and I was _46_ _.
The next day,I came home from work at about 6:30 pm and my wife asked me to go and get Kevin back __47__ she said he should be back home at 6. I walked to his friend's house and a look of __48__ appeared on Kevin's face when he came to the door.
At __49__,my wife and I spoke to Kevin about why he didn't come home on time again. He said he just wanted to _50__ playing. This was __51__,so we decided to ground(罚不准出门)him for a week. This __52_ no playing with his friends.
For the next week,whenever his friends came to ask for Kevin,we let him __53__ to them that he was grounded. We felt this would help him be responsible for his __54__.
As a __55__,I believe one of the most important things we can teach our kids is self-responsibility and that actions have consequences.
