I was listening to the radio while 1 was driving home from coaching basketball yesterday. I could tell right away that there was something  41  by the mood of the speaker. There had been a plane crash. What made the 42  even more tragic was that Bob Collins,the morning show man, was among those who had been killed. Throughout my 40-minute  43 , I listened as sincere love and affection from the audience  44 .The more I listened about how this man had influenced those around him, the more   45 I became.
That was because I wanted to know  46 we as a culture, wait until somebody has passed away before we tell them how much they  47 to us? Why do we wait until it is too late before we  48 someone up after they have died? Yes,49  memory after memory about someone's good  50 does help us cope with the sadness of losing someone special to us. But as we  51 remember this person, our words fall short of the ears that most need to hear  52 .
Just once,  53 a gathering of death,1 would like to see a celebration of life,  54 stories are told, tears fall down,laughter rings out;and as the speaker  55 his or her loving tribute(颂词), the person they are  56  rises from the chair and gives them a  57 hug! Wouldn’t that be   58 !
Life is too short to leave kind words   59 . How I wish that when the unavoidable funeral finally comes,we could say  60 with the knowledge that they knew exactly how people felt about them while they were here on earth.
