6、Several years ago, I worked for a trucking company as a driver. It was my habit to spend a couple of hours maintaining（保养） my truck on Saturdays. As I was under the truck greasing（上油） it, I noticed the owner’s elderly father making his way over to his grandson’s truck next to mine. 

   The old man was in his high eighties, had been a fishing-lover all his life, and had come out to ask the kid to take him fishing after work. The grandson told him all about how much he would love to do that, but he just couldn’t that day due to his tasks.. The old man accepted the answer and slowly went off to the house.

   A few minutes later, the father came out and asked his son what the old man had wanted. After telling the story, the kid ended it with telling his dad, "I’m not taking that old man fishing! It’s worse than taking a kid."

   That just broke my heart. I quit working immediately and got everything ready for fishing as quickly as I could.  After that, I went to knock on the door and invited him fishing.

Two weeks later, the old man died. His family told me later that all he talked about during that time was his fishing trip.
