Dialogue about merits and demerits of mobile phone

Shafiq	You seem very glad today. What is the reason?
Rafiq	Actually, my father bought me a new mobile phone yesterday. Here it is.
Shafiq	Nice, very nice. What do you think about mobile phone?
Rafiq	Mobile phone is a very essential [অত্যাবশ্যক] device. It has made our communication easy. It adds speed in our life. We can take photo; video and we can enjoy music from a mobile.
Shafiq	Recently introduced android and windows phone work like computers.
Rafiq	Yes. By using it, we can send e-mail and make video call. It has made our life easy and comfortable.
Shafiq	Right. It has reduced [হ্রাস] uncertain doubt, anxious [চিন্তিত] waiting and painful suspense [উদ্বেগ]. In fact, it has made our life easy and comfortable.
Rafiq	I cannot do without it for a single day.
Shafiq	Yes, you are right. But there are some demerits of mobile.
Rafiq	What are you talking about?
Shafiq	Now a day, mobile has become an easy way of teasing [উত্ত্যক্ত করা] girl. Some people commit crime using mobile.
Rafiq	Not these are only. Much use of mobile is harmful for health. It harms our hearing power, causes brain tumour, genetic damage and many other incurable [দুরারোগ্য] diseases.
Shafiq	During conversation, the blood brain barrier may get damaged, the blood pressure may get high and the red blood cells may get affected.
Rafiq	Even some students cannot concentrate in study because they talk over mobile the whole night.
Shafiq	Besides, it causes a lot of harm to the teenagers. They can easily contact with their so called lovers in season and out of season.
Rafiq	This point is also correct. Because the operators provide facilities [সুবিধা] at night.
Shafiq	But it is not the fault of mobile. It is our fault.
Rafiq	Of course. Though we are getting immense [বিপুল] benefits from it, we should use it with care and caution [সতর্কতা] to avoid its demerits.
Shafiq	I have to go now. It’s time for my private tutor.
Rafiq	Ok. See you later. Bye.
Shafiq	Bye.
