What’s your attitude to April Fool’s Day? A survey has done in our school and it shows that there are three different opinion. About 40% of the students thought it fun to have such a specially day to play jokes on each others. Besides, it adds many pleasure to our school life. At the same time, we can take this chance to test that our classmates are clever enough. But 30% of us don’t like the day because everything that seems in disorder and you don’t know whom to believe or how to do. Furthermore, most jokes are boring and some even go too far, but they often cause trouble or anger. The rest think people just play jokes; don’t too serious.
