whether mobile phone has reduced our lifes privacy?

For me, not really because there is always the switch off button which I'm not scared to use :P If I feel I don't want to talk to anyone I will just turn it off, I will set my voicemail message to busy or something and go back to bed LOL. If anything mobile phones have made my life much better, people don't usually turn off their mobiles so if I need to talk to someone I usually can plus if it's not something urgent I usually get text messages which I prefer so much more because I hate talking on the phone, I prefer to just read my messages like an email. And I am always getting my email through my phone now which is very handy.
