We hoped to enjoy ourselves there. However,some of the people there makes me feel very unhappy.When we arrived there, the movie been on for ten minutes. We found our seats quick and sat down. What's worse,a few guys were talking loudly or even shouting when they saw some excited pictures. Also, some people threw away plastic bag, paper and other rubbish on the floor, that made the floor very dirty.As we know, the cinema is a public place where we can have a nice time. All of us are supposed to obey the rules in the public. Only in this way can we make public places more comfortable.
