How difficult is it to go ‘off the grid’ in a modern society. Easier than you think. IE on a missing Australian teenager:

Queensland Police posted about the missing teen Sunday, asking citizens on the social network to contact them if they had any information about the girl.

Not long after the police began looking for the air she responded:

Guys I’m fine I’m not missing this is an overreaction to a fight I had with my sister, I’m legit just sitting in my bedroom.
