I'm 14 and don't actually own a mobile phone or want one anytime soon, and have turned down my parents offers for one, pretty much for the reasons stated above. Pretty much all my friends are facebook and text junkies and have all been begging me to get a mobile for the last 3 years, but If I did it would mean getting involved in all the drama they have about boyfriends, break ups, sex, alcohol and blah blah blah which I've managed to keep out of my own free time so far. And plus I wouldn't want to have to pay all the bills when I don't need too. This way I can also avoid random *spot checks* by my parents.
I have my own laptop and to be honest I only send emails to my friends abroad and go on msn only in the evenings and most of the time spent using the computer is something to do with horses :)
My dad is pretty much what your whole text is about, except since he was your typical boy he spend half his time throwing makeshift bombs and stinkbombs into crowds and running off and climbing up tree's and doing pretty much everything outside, so I get the *everythings changed* speach alot
