I can't restrain myself from explaining the incident that happened last night. I went out with few of my friends. We were two girls and three boys. But we had only two bikes. So two of us shared one bike and other three the second bike. It was 11:00 o'clock in the night. In India it is illegal for three persons to travel on one bike. Usually at this time there are no traffic policemen. But yesterday, unfortunately, we encountered one. I, who was sharing bike with two more fellas
had to fake unconcious. Then the other two on bike told him that we have to see a doctor urgently for my medical condition. I kept my eyes close. Then he let us go without asking for a fine. Then after we were out of the policemen reach i turned back and saw that three persons sitting on a same bike trespassed the policemen with a very high speed. And surprisingly the policemen didn't even bother to look at them. Our effors were vain. But it was a thrilling experience.
