　　It was early December and I was driving my children over an hour to a distant mall (商场) to do some Christmas shopping. We were finally nearing the exit that would tas there. I smiled and sang quietly along to the song playing on the radio.
　　Then I noticed an older woman in worn, dirty clothes with a big sadness in her eyes at the end of the highway exit holding a sign. “It is probably someone trying to catch a ride south,” I thought to myself. When I got close enough to read it, however, I saw that it said, “Homeless. Please help. Willing to work for food.”
　　I took my children into the mall, but all the Christmas spirit had left my heart. I couldn’t stop thinking about the woman by the exit, standing outside in the cold, without a home.
　　Later after we left the mall my children and I stopped at a local store to buy some food for the long drive back home. When I got to the exit that would get us back on the highway, though, I found myself driving past it and back to the exit we had driven in on. She was still there holding her sign. I pulled off the side of the road, pulled out the money I had left in my wallet and gave it to my daughter beside me. She then rolled down her window and gave it to the lady. The woman stood there with the money in her hand and thans. Before she could finish her sentence my daughter reached out and gave her the food she had bought for the trip home.
　　We pulled bact on the highway. None of us felt proud or even happy with what we had done. We only wished we could have done more.
