My opinion differs from my classmate's one. Nastya thinks that the phone is the the best and the most convenient means of communication which we use. In my opinion with the phone appearing in our lives we have become more stupid. For example, my classmate is mobile-addicted. He uses the mobile phone as a cure for boredom, but this pastime dominates in his life. He has been dealing with this addiction since 5-th form. Is that phone exiting to make him completely forget about the reality? I don't think so. Did you know what this simple means of communication could be dangerous too? Spending all your time on telephone may lead to stress and even problems with sleep. I can say that mobile phones are wolves in sheep's clothing. This addiction doesn't show any physical symptoms, but can affect you psychologically.
