Everyone enjoys going to the cinema to watch movies for entertainment. However,watching movies can be a viewer's nightmare. First of all, we could hear cell phones ringing although viewers are not allowed to switch on their cellphones in the cinema. The ringing is very distracting to us especially when we are trying hard to concentrate on the movie. Secondly,some viewers are restless.They keep shifting the position of their body when they are seated,and sometimes they accidentally touch you. This is very annoying indeed when your viewing is suddenly disrupted by your inconsiderate neighbor. Finally, some viewers often love to talk about the movie even while the movie is playing.They make comments and they even predict how the movie would end. For these reasons, going to the movies is sometimes not pleasurable.
