A woman saw three old men sitting outside the door. She said, “I don’t think I know you, but you must be very hungry. Please come in and have something .”

“We don’t go into a house ”，they replied. “Why is that?” she asked.

One of the old men answered, “His name is Wealth(财富), this is Success, and I am Love.” Then he said, “Now go in and with your family which one of us you want in your house.”

The woman went in and told her family what had happened, she said, “Let’s invite Wealth. We are so .” Her husband disagreed, “My dear, why don’t we invite Success? Don’t you want me to be a successful man? Then her daughter asked, “Would it be to invite Love? Our life will then be filled with love!”

In the end the family decided to take the advice. The woman went out and asked, “ one of you is Love? Please come in and be our guest.” Love got up and started walking to the house. The other two also got up and him. Surprised, the lady asked Wealth and Success, “ I invite Love. Why are you coming along? The two old men answered, “If you had invited Wealth or Success, the other two would have to stay out. But since you have invited Love, he goes, we go with him. Where there is Love, there is Wealth and Success.”

My mother used to ask me what the most important part of the body is. When I was younger, I thought s 1. was very important to us as humans, so I said, “My ears, Mommy.” She said, “No. Many people are deaf. But you keep t 2. about it and I will ask you again soon.”

Several years p 3. before she asked me again. This time I told her, “Mommy, sight is very important to everybody, so I’m sure it m 4. be our eyes.” She looked at me and told me, “You are learning fast, but the answer is not correct because there are many people who are b 5. .”

Over the years, Mother asked me some more times and a 6. her answer was, “No, but you are getting smarter every year, my child.”

Then last year, my Grandpa died. Everybody was crying. My Mom looked at me when it was our turn to say our f 7. good-bye to Grandpa. She asked me, “Do you know the most important body part yet, my dear?”

I was shocked when she asked me this now. I always thought this was a game between her and me. She said, “This question is very important. It shows that you have really lived y 8. life.” I saw her eyes were filled with tears. She said, “My dear, the most important body part is your shoulder.”

I asked, “Is it because it holds up your head?” She replied, “No, it is because it can hold the head of a friend or loved one w 9. they cry. Everybody needs a shoulder to cry on sometimes in life, my dear. I only hope t 10. you have enough love and friends. Then you will have a shoulder to cry on when you need it.”

Then and there I knew the most important body part is not a selfish one. It is sympathetic to the pain of others.
