Technology plays a huge part in education, recreation, and social connection for teenagers. There will be so much you want to warn them about, but remember to boil it down to a few simple messages to avoid a complete overload.
"You're the same person online as you are offline" is a really important one. The illusion of anonymity and the speed with which information can be spread can tempt anyone to say or do things they wouldn’t do in person. Make sure your teen understands what integrity means: I'm the same person, with the same standards, no matter whether I'm online or offline.
