How an unbelievable scene ! A modern young couple were eating fruit in public and had thrown a plenty of waste on the ground. When an old cleaner comes to clean up, the man was very angry. He pointed at the cleaner, said in a loud voice," How impolite! They haven't finished eating!" " How could people behave such badly?" I thought. Obvious, in their eyes, they could do all they liked and ignore other's feelings. In my opinion, we should pay attention our behavior, obey public rules and respect other's works. We should know that really civilized people are those who have good manners but a beautiful mind all the time.
