Jahid : Hi, Shuvo! How's everything?

Shuvo : Fine. Thanks.

Jahid : What're you doing?

Shuvo : I'm using facebook.

Jahid : What's the use of facebook?

Shuvo : It's a social media and one of the best ways of communication. Facebook gives me the opportunity to share my ideas, feelings, activities and interest with others.

Jahid : Is there any other benefit?

Shuvo : Of course. By creating group, students can do group study. They can share any information about homework, assignment, exam, etc. in the group with friends.

Jahid : I see. But is facebook free from demerits?

Shuvo : Of course not. Every social site has its uses and abuses. Many people get addicted to using facebook. Thus they kill their valuable time. Young people often spend a lot of time by chatting unnecessarily with other people.

Jahid : Using facebook for a long time may weaken our eyesight, right?

Shuvo : Yes. So, I think we should be cautious about using facebook.

Jahid : Certainly. We shouldn't misuse it.
