     She was returning from teaching out in a small community (社区). It was a black, moonless night, and

a heavy snow was falling.

     She thought back to the time when she had first started teaching out in small communities. During those

days she had always picked up hitchhikers (搭便车者), until the day her sister told her that one of her friends

had been shot (中枪) in the head by a hitchhiker, all because she had stopped out of kindness to help him

during a storm.

     Her family didn't stop worrying about her safety over the hitchhikers until the family heard the promise:"

No more hitchhikers!" The snow that night was making her think back to this.

     Then she saw a man waving. She slowed down for him, but as he ran toward the car in the dark, she

shook with fear. Yet she thought that if he was truly in need, she couldn't leave him here in this storm.

     The stranger explained that his car was dead, and she told him to get in. They drove for an hour into the

next city and she took him to a telephone booth (公用电话亭). She waited until he had made a call. When he

reported back to her that a family member would soon come to pick him up, she wished him well and then left.

     Tears fell on her cheeks as she drove away. It felt as though she had been holding her breath for an hour.

"I hope they'll understand why I had to break my promise," she thought.
