Many people used to gather to dance in our community square, where was designed to improve living quality. Although dancing could do good to their health, but the long-time dancing and loud noise causing by the loudspeaker really brought the neighbors inconvenience. I couldn’t rest or sleep well, which made me terrible upset. I felt such sleepy in class that I performed badly in study. To solve a problem, I communicated with the organizers and suggested that they should shorten the dance time and reduced the music noise. Only doing so could they have fun and let others enjoy life. To their delight, they adopted my advices.
