Checking their phones is lesser of two evils
When I was a teenager I kept a diary. I knew that it was safely locked away in my bedside locker. I never had to worry about someone breaking into my house, reading it and then telling everyone about it.
Nowadays, teenagers communicate every feeling and image via phones, iPads and laptops. They are obsessed with sending images of themselves to each other. They know of no way to communicate other than digitally.
So how do we keep our teenagers safe from hackers, stalkers, sex-texters, bullies and anyone else out there who wants to harm or humiliate them online?
