"The Cloud"
You've probably heard it said that the world has gotten smaller. This is true because, since the development of the Internet (the 'Cloud') and such things as Tweeting, texting, instant messaging, social networking (Facebook, Instagram), we've grown much closer.

Most people are good - but it's easier than ever for those that aren't to target people who aren't prepared, or aware of the dangers.
