阅读下面短文，根据所给语境，按要求完成下列各题。
A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.
“Daddy, how much money do you make an hour?”
“If you must know, I make $20 an hour,”
“Oh,” the little boy replied, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me $10?”
The father was furious, “If you asked for the money to buy a toy or some other rubbish, then go straight to your room and think about why you are being so selfish（自私的）!”
The little boy quietly went to his room and shut the door. After about an hour or so, the father calmed（平静）down, and started to think, “Maybe he really needs to buy something and he didn’t really ask for money very often.” So he went to the little boy’s room.
“Sorry! Maybe I was too hard on you just now.” said the man, “Here’s $10.”
“Oh, thank you, Daddy!” he said happily. Then, the boy took out some coins. When the father found that the boy already had money, he got angry again.
“Why do you want more money since you already have some?” the father shouted angrily.
“Because I didn’t have enough, but now I do.” the little boy replied, “Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you.”
