At first I was worried you were the kid... then I looked at your profile and saw your age... I knew you were the parent and guessed what the issue was... I am glad to have helped.
you're lying about your age. Go to your room!
If your tweets need scrambling, then you're dealing with the wrong people... Get a grip.
If you are worried about your parents reading your tweets, then maybe you're not old enough to be tweeting! Or, you shouldn't post things you wouldn't be comfortable with your patents reading....
I'm 42.... Old enough to do as I please... And I wouldn't care that my parents read that I'm proud of my 36Ds, which they gave me :)
Why not take his phone away? I am 22, but I think teens are creeps and mostly up to no good. (I know first hand). Parents are stupid to give them text messaging.
It's amazing how easily those expensive phones accidentally fall into the water when you are not careful. It's a shame it ruins them where they cannot be used again.
