This is Emmet. He is a young boy and he loves the internet! He is in ChinaTown and heads for a noodle bar.

Some random Game thing. lolololololololololol
Whist as the noodle bar, he pulls out his phone. He sees that they have free wifi but it he didn't realise it was insecure.
As he turns his phone on, someone from the otherwise side of the world was watching him. From his phone.
This person was cyberstalking. He was tracking Emmet's digital footprint. He was tracking his Location, what apps he had been using and as the wifi at the noodle bar was insecure, he had access to Emmet's phone.
Whilst at the library, his phone gets a ping. And another... And another...And another! It soon got out of hand he was even ejected from the libary!
Emmet was worried. He then looked for help. Luckily he sat with a trusted adult and discussed it. He found out about these cool privacy setting. However the Cyberstalker had... less fun.
