　　My first full­time job after high school was selling vacation packages(旅行产品) via the telephone for a well­known company. One day，I was put through to a man who sounded a bit out of breath. I started with my normal pitch(音高)，expecting to hear the normal reply-"I don't want any."

　　Instead，he spoke in a faint，weak voice and told me how he wished to take a vacation I was offering，but he couldn't because he was dying of illness. He explained how he was lacking in oxygen then，and it took almost all his energy to answer the call. He asked if I smoked，which I did，and begged me to stop. He told me smoking was what was killing him. He told me to spend every day with my loved ones，and tell them how much I love them. At this point，I couldn't control myself. We ended the call，but I held on my phone to prevent another call coming in so I could collect myself.

　　I wrote down his name and address，and sent him a card appreciating his advice and praying for him and his family. Shortly after，I received a letter from Frank，along with a picture of him and his wife. We continued to write back and forth over the next few months，and became very fond of each other. He was old enough to be my grandfather，and in many ways，I felt as if he was.

About a year later I received a letter from his wife. When I started to read，tears came to my eyes. She told me how Frank's battle with the disease had finally come to an end，and he passed away shortly before the Christmas. She wanted to thank me for the letters to Frank，and explained how Frank touched many lives over the years. At his funeral，to show just that，they read the 1st letter I had written to Frank to show how he affected a 19­year­old boy he'd never met.
