   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!”
   The little boy quietly went to his room and shut the door. After about an hour or so, the father calmed down, and started to think, “Maybe I was too hard on you just now.” said the man, “Here's $10.”

   “Because I didn’t have enough, but now I do.”the lillte 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.”

卜算子 张元幹①

万古只青天，多事悲人境。起舞闻鸡②酒未醒，潮落秋江冷。

【注】①张元幹，宋代爱国词人②起舞闻鸡：出自《晋书·祖逖传》：传说东晋时期将领祖逖年青时就很有抱负，每次和好友刘琨谈论时局，总是慷慨激昂，满怀义愤，为了报效国家，他们在半夜一听到鸡鸣，就披衣起床，拔剑练武。
