What is a friend to you ?

This is the question we're asking for the new project, in cooperation with Nokia.
In the Only Planet program, they want us to investigate our communities looking
for how people communicate in different ways.
Our group, formed by me - a Brazilian, Ule Chong (Chinese/ Malaysian) and
Rahul Sen ( Indian) decided to look back into our origins and dig characteristics
and stories, focusing on all those that are still not connected by whatever media.

Mixing them up, we wish to see what can we find that is common to these
three cultures. And so far we came up with the concept of a friend.

Please share your particular definition on this broad concept by
posting a reply here. Thank you very much, my friends.
