I was captured by the enemy and thrown into a jail cell. I was sure from their looks and 36 treatment that I was to be killed the next day. Terribly nervous and worried, I felt in my pockets to see if there were any cigarettes, which had 37  jailers' search. Surprisingly, I found one. But because of my shaking hands, I could 38 get it to my lips. After several attempts, I finally succeeded, but almost immediately 39  that I had no matches. They had taken those away from me.

I looked through the bars at my jailer. He did not make eye contact with me. 40 one did not care to see a dying man. I 41 out to him, "Have you got a light?" He looked at me, shrugged and came 42  to light my cigarette.

43 he came close and lit the match, his eyes unintentionally 44  mine. At that moment, I smiled. I don't know why I did that. Perhaps it was 45 , perhaps it was because, when you get very close, one to another, it is very  46   not to do that. In that instant, it was as if a spark(火花)jumped across the  47  between our two hearts, our two human souls. I know he didn't want to, but my smile leaped through the bars and  48  a smile to his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile. I kept smiling at him, now  49  of him as a person and not just a jailer.

My eyes were filled with  51 . I said that I feared that I'd never see my kids again, never have the chance to see them  52  up. With my words, his eyes turned wet, too. Suddenly, he    53  my cell and silently led me out. Out of the jail, quietly and by back routes, out of the town. There, at the 54 of town, he released me. And without another word, he turned back toward the town.

My life was saved by a smile.

Yes, the smile, the unaffected, unplanned, 55  connection between the souls of people, actually saved my life.
