Classes are always interesting and useful to attend as they enhance our knowledge for our better future and life. Some students like to attend the classes in which teachers take lectures and there is no talking with the students. While some students would like to attend the classes in which they also do some of the talking such as asking their doubt or reading any book chapter. As far as I am concerned, I like those classes in which students are also allowed to do some talk instead of sitting silently all the time. I think this way for two reasons, which I will explore in this essay.
