Being responsible is actually not that difficult. I used to think it is hard to grow up into a responsible member of our society. An incident happening in a rainy Sunday afternoon changed my attitude. I was on my way to the bookstore and was waiting for the green light while a girl was knocked down by passing car, which drove off quickly. A man immediately gave her first aid and I had joined in without hesitation. Soon many help was given to the girl. Because we sent her to the nearest hospitals in time, she was able to receive properly treatment. Not badly injured, I expressed gratitude to those giving help. Compared with the escaping driver, I was proud of what I did.
