Years ago,when I was working as a psychologist (心理学家),a boy

Years ago,when I was working as a psychologist (心理学家),a boy showed up in the waiting-room.It was David,who was looking down at his feet nervously.
David had lived together with his mother and grandfather since he lost his father.But when he turned 13,his grandfather died and his mother was killed in a car accident.He became very 37,refusing to talk to others from then on.
The first two times we met,I did most of the 38 ,but David didn't say a word.He just sat in the chair and was even careful not to allow our eyes to meet.When he was going to 39 after the second visit,I put my hand on his shoulder.He accepted it,but still didn't 40 me.
When he came the next week,I suggested playing a game of chess.He agreed.After that we played chess every Wednesday afternoon - in complete silence.It was not 41 to cheat in chess,but I managed to let him win once or twice.
But why did he 42 look at me?"Perhaps he only needs someone to 43 his pain (痛苦) with," I thought.I kept wondering and playing with him,until some months later,suddenly,he looked up at me,"It's your turn," he said.That made me 44 because I could see the hope of success.
After that day,David started talking.Soon he got a lot of 45 in school and joined a bicycle club.He wrote to me several letters about how he would try to get into university.After some time,the letters 46 .I knew he had really started to live his own life.
Maybe I gave David something.At least I learned a lot from him.He 47 me how one – without any words – can reach out to another person.All it 48 is a shoulder to cry on,a friendly touch and an ear that listens.
