     When I was an educational official in Palo Alto, California, Polly Tyner, the president of our

school board, wrote a letter that was printed in the Palo Alto Times. Polly's son, Jim, had great

difficulty in school. He was classified as educationally disabled and required a great deal of

patience on the part of his parents and teachers. But Jim was a happy kid with a great smile that

lit up the room. His paront8 acknowledged his academic difficulties, but always tried to help him

see his strengths so that he could walk with pride. Shortly after Jim finished high school, he was

killed in a motorcycle accident. After his death, his mother submitted (提交) letter to the newspaper.

     Today we buried our 20-yeer-old son. He was killed instantly in a motorcycle accident on

Friday night. How I with I had known when I talked to him last that it would be the last time. If I

had only known I would have said, "Jim, I love you and I'm very proud of you"

     I would have taken the time to count the many blessings he brought to the lives of the many

who loved him. I would have taken the time to appreciate his beautiful smile, the sound of his

laughter, hit genuine love of people.

     When you put all the good qualities on the scale and try to balance all the irritating phenomena

such as the radio which was always too loud, the haircut that wasn't to our liking, the dirty socks

under the bed, etc., your angry feelings won't amount to much.

     I won't get another chance to tell my son all that I would have wanted him to bear, but, ether

parents, you do have a chance. Tell your young people what you would want them to hear if you

knew it would be your last conversation. The last time I talked to Jim was the day he died. He

called me to say, "Hi, Mom! I just called to say I love you. Got to go to work. Bye." He gave me

something to treasure forever

     If there is any purpose at all for Jim's death, maybe it is to make others appreciate more of life

and to have people, especially family members, take the time to let each other know just how much

we care.
