Can I survive without my phone?

I'm addicted to mi Iphone, that's something a little bad  because I'm always aware of what my friends send to me in WhatsApp or if I had a notification  in Instagram. I really like to post things in Instagram, it's my favourite social network.

When I was in Peru I hadn't my phone so I demostated to myself that I can live without mobile. But I have to recognize that the first thing that I do when I arrived to my home was look my Iphone.

I think the booth of teenagers had a little obsession with their phone. I don't know anybody who hasn't got one of this social networks: WhatsApp, Twitter, Facebook or Tumblr.

A good discussion could be if mobile phones are indispensable or not. People have lived a lot of years without they but we all can be agree that it's a good invent.  Another question is if students need the phones in high school. One day which was raining a lot I don't carry with me my Iphone, because I have P.E, and I had to go home alone in the rain. I f this day I had carry my mobile I hadn't wet. That's why my position to the question is yes, it's necesary. That don't make that I don't  find cons, for example we can't use it in class, and chat with friends or take photos. I don't want to be hipocrite, and I confess that I have break the rules.
