Mobile phone: good or bad?

mobile has both advantage and disadvantage...it is useful by simply keeping in pocket we can contact around the world but disadvantage is less compare to advantage

I think it is a good invention except that people abuse it. I hate it when my ex boss terrorise me with the phone and at that time I hate the mobile phone. She is an old and crazy woman whom loves to terrorise people on the phone and gets upset when we switch it off or ignore her calls. She gets mad and gives us lashings for doing that but nobody cares about her simply because, the mobile phone is ours and we paid for it. She is absolutely in no position to scold us for that matter. That old witch.
