Do you know how quickly you can ruin someone's life? In two seconds, the time it takes to share a photo on WhatsApp. You already know this, you've had the talks on cyberbullying, it would never happen to you, it's boring to keep hearing about it, right? That's exactly what Glauca thought. What was wrong about sending a photo to her boyfriend if they loved each other very much? What she didn't know was that her boyfriend would show it to Andrea. And that Andrea who hates her with every fibre in her being, would share it with more people and then would upload it onto the internet to make her into a laughing stock for everyone. And on the internet, your life instantly ceases to be your own. But Andrea wasn't counting on the fact that, when Glauca was just about ready to throw in the towel, someone would fight tirelessly for her. . . and would offer her a blue umbrella.
