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.
