Values join us together and set us apart. Today, our society has a terrible lack(缺乏)of values. Here are some social values that everyone needs.
◆Respect
Respect means to respect(尊重)others in everyday life. Even if you are against a person, it is important to have respect. It is this respect that makes us human. Without this respect, we become  animals. We need to respect our friends for our friendships. We even need to respect our enemies, because they help us to grow up and be stronger. Respect is one of the crucial values in a relationship.
◆Love
Love is everything. With love in our hearts, we feel no need to hurt another. With love in our hearts, we will pay more attention to the similarities in opinions rather than the disagreement. If we want others to be good to us, we need to be good to them. After all, we give love to get love, right?
◆Loyalty
People often forget the meaning and importance of loyalty(忠诚). Loyalty is necessary for people to believe in each other. In no matter what kind of relationship, we need to believe in each other so that we can work together towards the same goal.
◆Honesty
Honesty is to show other people who we really are. Honesty helps us do better, because it makes us realize our problems and find ways to solve them. It is this honesty, that will make others help you out, not because you need it. But, because they have problems too, which you can help out with. This honesty will help us follow the other values in society and, truly, "heal the world"!

B

    I'm David. Long ago I came to the city near my hometown to find a job. I met all kinds of difficulties and I used up all my money soon.

    It was dark outside one day. I got on a bus quietly. Suddenly, a passenger cried in a loud voice, "someone has stolen my money!" I felt nervous, because his money was in my hand. Some people suggested the driver drive the bus to the police station, but some were against it because they were in a hurry to go back home. The whole bus was very noisy. The driver then stopped the bus by the roadside and turned on the lights. At that time, one passenger said, "Turn off the lights and give the thief(小简)a chance to take out the money."Then the bus got dark.

    When I was still thinking about whether to take out the money or not, the lights were turned on again. There was no money on the floor. Someone said, "Give him one more chance." Then the lights were turned off again. I became even more nervous. The lights were turned on again but they got the same result.

    Then the passengers fell into an open discussion. Later, someone said, "Give him the last chance!" I felt awakened(醒悟的) and took out all the money when the lights were turned off again.

    For many years I have been grateful to those who gave me three chances. When the first and Second chances come, you may not be prepared well or don't have enough courage to act. When the third chance comes, you should know clearly what you should do.
