Mr. Brown had much money. One day he went on a trip to the countryside with his 5­year­old son Eric. He wanted to show his son how poor people lived, so they spent a day and a night on the farm of a very poor family.

    When they got back from their trip, Mr. Brown asked Eric, "My dear son, how was the trip?"

    "Very good, Dad!" Eric said happily.

    "Did you see how the poor lived?" Mr. Brown asked.

    "Yeah!" Eric answered.   "And what did you learn?" Mr. Brown asked.

    "We have a dog at home but they have four. We have a pool that is in the middle of the garden but they have a river that has no end. We have expensive lamps(灯) in the garden but they have the stars, "Eric answered.

    When little Eric finished, Mr. Brown couldn't say anything.
