      A woman saw three old men sitting in her front yard. She said, "I don't think I know you, but you

 must be very hungry. Please come in and have something to eat."

     "We don't go into a house together," they replied.

     "Why is that?" she asked.

     One of the old men answered. "His name is Wealth, this is Success, and I am Love." Then he said,

 "Now go in and discuss with your family which one of us you want in your house."

     Then the woman went in and told her family what was said. She said "Let's invite Wealth. Let him come

  in and bring us nice things. We have been so poor. "His husband disagreed, "My dear why don't we invite

 Success? Don't you want me to be a successful man?" Then the daughter asked, "Would it be better to

 invite Love? Our life will then be filled with 1ove!" "Let's take our daughter's advice (建议),"said the

 father and mother.
