It was my 17th birthday and I was looking forward to see my friends. I arrived at my favorite restaurant, waiting for him. We would have the special birthday dinner. I looked for a familiar face but failed. Soon the restaurant was filled customers, none of which were my friends. An hour later, I went back home, lonely and disappointing. To my great surprise, I found the door was wide open while I arrived home. Nervously, I walk into the dark room. Suddenly, all the light went on and my friends were appeared shouting ‘‘surprise”. I had an unforgettable birthday.

When I look at this picture of myself, I realize of how fast time flies. I had grown not only physically, and also mentally in the past few years. About one month after this photo was took, I entered my second year of high school and become a new member of the school music club. Around me in picture are the things they were very important in my life at that time: car magazines and musical instruments. I enjoyed studying difference kinds of cars and planes, playing pop music, and collecting the late music albums. This picture often brings back to me many happy memories of your high school days.
