The Stranger Who Changed My Life
It was a sunny morning in the spring of 1966. I was driving a taxi，looking for a customer. While passing New York Hospital，I found a man running down the hospital steps，waving at me.
I stopped. The man reached the taxi and jumped in. “The Airport，please.”he said. As always，I wondered about my passenger. Was this man a talker？ After a few moments，he started saying， “How do you like driving a taxi？”
“it’s OK，”I said. “I make a living and meet interesting people sometimes.”
“ What do you do？” I asked.
“I am a doctor at New York Hospital. ”
Many times during long rides，l’d developed a good relationship with my passengers and received very good advice from them. This time I decided to ask for his help，“Could I ask a favor of you？ ”He didn’t answer. “I have a son，15，a good kid. He wants a job this summer. is it possible that you get one for him？”
He still wasn’t talking, and I was starting to feel foolish. Finally, he said, “ Well, my students have a summer research project. Maybe he could join in. Have him send me his school record. ”
He left his address and paid me. It was the last time I ever saw him.
