Twenty years ago,I drove a taxi for a living.I met  2l  people.But none touched me  22  than a woman I picked up late one night.
I received a call from  23 in a quiet part of town.When I arrived at 2:30 a.m.,the building was  24  except for a single light in a ground floor window.I  walked to the door and  25 .“Just a minute,”answered a  26 ,elderly voice.After a long pause,the door opened.A small woman  27  her 80s stood before me.Beside her was a small suitcase.I took it to the taxi.and then returned to  28 the woman.She took my arm and we walked  29  toward the roadside.
Seated,she gave me  30 .“I’m on my way to a hospice(临终关怀医院).I'm in no hurry.Can you drive through downtown?” I saw her eyes shining with  31 in the rearview mirror.“I don’t have any  32  left.”she continued.“The doctor says I don’t have very long.”
During the next two hours’ 33 , sometimes she asked me to  34 in front of a particular building or corner and she  35 stare into the darkness.When we got to the destination,she asked,“How much do I   36 you?” “Nothing,”I said.“You            37 make a living.”she answered.“I have  38  passengers,”I replied,and gave her a hug. She held onto me  39 .“You gave an old woman a little moment of joy,” she said.“Thank you.”
After that,I drove aimlessly,lost in thought.People usually believe that our lives center upon great moments.  40 great moments often catch us unaware,beautifully wrapped in what others may consider a small one.
