    The International Volunteer Day approaching  some volunteers of our school are organized to assist the policemen with traffic control in our city. At 8 o’clock on the morning of last Sunday we gathered at the school gate. One of our teachers was in the charge of this activity but he divided us into four groups. Then we went to different crossings near our school. The police officers told us that we should do and how to protect themselves from danger. We spent the whole morning keep the streams of traffic flowing smooth. With a red banner in our hands we stopped some road user running the red light. Some citizens praised us our good deeds. Because we were very tired that morning we were proud to have offered service to our society.
