    Long ago, three pigs grew up and left their parents' home. They said goodbye to each other and went their separate ways.

    Each little pig decided to build a house. The youngest pig was lazy and he thought, "I will build my house with grass. It is light and easy to build with." The middle pig thought, "Here are many small sticks. They are easy to work with. I will build my house out of sticks." The oldest pig worked hard and always thought before doing things. "There are many dangers（危险）in this world. I must build a strong house out of stones," he thought.

    And soon, the three pigs built their houses. One day, a big wolf（狼）came to the town. He was very hungry. He saw the first little pig in his grass house. He pushed down（推倒）the house and ate the little pig. Then the wolf came to the stick house and pushed it down, too. Then he ate the second pig. When the wolf came to the stone house. He pushed it again and again. But he couldn't push it down. In the end, the wolf gave up and went away. The oldest pig lived a long and happy life.

    One day, I walked into a stranger as he walked by me. "Oh, excuse me." I said. He replied with a smile and said, "Please excuse me, too. I wasn't watching out for you." We apologized(道歉) and went our own ways.

    Later that day, when I was cooking, my daughter was standing too close to me. When I turned to reach for some milk, I nearly knocked her over. "Move out of the way." I shouted. She walked away sadly. But I didn't feel like I had to apologize to her.

    While I was in bed that evening, my husband said to me, "Dealing with a stranger, you were polite, but with a daughter you love, you were unkind. Your daughter brought you some flowers that she picked herself this afternoon. You'll find them in the kitchen by the door. Have you seen the tears in her eyes?"

    I quietly went and knelt down by my daughter's bed. "Honey, I am so sorry." I said, "Are these the flowers you picked for me?" She said, "I found them by the tree. I picked them because they're pretty like you. I knew you'd like them especially the blue ones." I tearfully replied, "Sweetie, I'm really sorry for the way I acted today. I shouldn't have shouted at you." "It's okay. I love you anyway." she said as she kissed me on my cheek.

    If we can be polite to strangers, why can't we be kind to the ones we love?

    One day, 100 people were attending a speech. The speaker was making a speech about happiness. However, after a few hours, people began to lose their attention. The speaker thought of an idea. He stopped his speech and asked all of the people to take part in a group activity.

    He gave each person a balloon in the room. Each person was asked to write his or her name on the balloon with a black marker (记号笔). Then, all of the balloons were collected and moved to another room.

The 100 people were then let into the room and told to find the balloon with their own name

    Everyone rushed around, crazily searching for their own balloon. People were bumping into and tripping (绊倒) over each other.

But after about five minutes of searching, no one could find their own balloon.

    After seeing this, the speaker asked each person to collect a balloon and try to find the person, whose name was written on it. Everyone started talking to each other and asking each other for their name. In just a few minutes, everyone had his or her own balloon.

    "Can you see what happened?" the speaker said. "The balloons are like the happiness we look for in our own lives. Everyone is busy looking for their own happiness, not caring what happens to others. But sometimes the best way to find happiness is to help others. Help them find happiness and you can find your own."
