Where did my friends go?

Where did my friends go?
Do you want to look deeper? And if there was no internet?
Do you know where your friends are, like before? Before sms, mails, tweets,...?
I wonder if one exists, without any online profile.

Just to make you think, some numbers: World population - around 7 Billion; Using the Internet - around 35%.
