Lost in the music, I did not realize that I had been standing for so long. But my existence did not seem to disturb her. Leaves were still falling. Every day when I passed by the lawn, I would see her playing her guitar. She was the only performer and I was the only audience. During the rest of the days in the season, life became interesting and I could review the courses carefully. Though we did not know each other, I thought we were always good friends.

It was the golden season. I could see the yellow leaves falling with the cool wind. For others, it is a harvest season, while for me, it is an annoying season. I was preparing for the Postgraduate Entrance Examination. But so many unhappy things made me so tired, so I decided to have a walk along the Yanjiang Road in my university.

"Autumn is a lonely season and life is uninteresting. The days in this season always get me down," I thought when the sound of a guitar flowed into my ears, like a stream flowing from the mountains. I was so surprised that I ran to see what it was. A young girl, sitting on the lawn, was lost in playing her guitar. She was a beautiful girl, especially when the wind blew her long hair. I had never seen her before. The music was so attractive that I listened quietly.

"You must like the music." she said.

"Yes, you play very well. Why did you stop?" I asked.

"I came here just to have a rest because I failed in the college entrance examination. I felt very disappointed. And it was your listening every day that encouraged me," she said, "and I have to go tomorrow."

Autumn was nearly over. One day, when I was listening devotedly, the sound suddenly stopped. To my astonishment, the girl came over to me.

Suddenly, a sad expression appeared on her face.

She smiled and I smiled.

"In fact, it was your playing that gave me a meaningful autumn and helped me believe that I have the ability to pass the Postgraduate Entrance Examination." I answered, "I think it was God who gave us the chance to know each other and we should be good friends."

Since then, I have never seen her again. I no longer passed by that lawn. Only thick leaves were left behind. But I will always remember the season and the girl. It was her appearance that helped me passed the Postgraduate Entrance Examination, though she only appeared a few days in my life.

I shall always recall the autumn, the girl and the sound of her guitar. I know she will always be my best friend.

We may encounter many people in our lives. Some are like a shooting star, but give off so much light that they guide you in the correct direction; some are like clothes to you, they are always with you, but do not understand you. Just as a famous saying, many people step in your life, but only true friends leave footprints.
