 One year ago. I asked a worker to help me repair my old house. He had a bad first day on the job: his car broke on the way, then he found he had left his tools for work at home and his wife telephoned to say his son had a bad cold. While I drove him home, he was silent all the way. When arriving, he invited me to meet his family.

As we walked towards the front door, he stopped at a small tree, and touched the tree with hands. When we opened the door, I was very surprised to see he changed into another person and there was a big smile on his face instead. He hugged (拥抱) his son and gave his wife a kiss.

After a while, when he walked me to the car, I asked him why he had touched the tree just then. "Oh, that's my trouble tree," he answered.  "Sometimes I have troubles on my job, but one thing is for sure, they don't belong to my wife and my son. So I just hang up (悬挂) the troubles on the tree every night when I come home. Then in the morning I pick them up. "

“The funny thing is," he smiled, "when I come out in the morning to pick them up, I hardly remember what I put the night before. "
