Nowadays, cellphones plays a big role in our society not just for students but to each and everyone of us. Despite of the advantages that cellphones brought us it has also many disadvantages. On the other hand, cellphones are very useful especially among students but some uses are very abusive. A lot of students didn't use cellphones properly like inside the classroom without the consent of the teachers. This way, can insult our teachers specially when their discussing in front and some aren't listening. So the question is "Why should we allow students to bring their phones in the school when they're very abusive in using it?" By this, we should tell the students not to bring their phones inside the classroom so that the teachers will not feel insulted and the students can concentrate in the class discussion.
