It seems nothing I do is private and I am hounded at every turn. Now they want to make my private correspondence available to all and sundry. Fair enough, look at the stuff I sent to government ministers, but lay off my One Direction fan mail, because that would be a step too far.
There is nothing more incriminating than a handwritten note, especially one showing a crude interpretation of your geography teacher with a swastika on his face doing bad things with a sheep. It might get you the adulation of your classmates for an afternoon, but be prepared to destroy it as soon as possible unless you want to do some serious explaining when you accidentally hand it in with your urban demographics homework.
Hope that helps!
