What do you think about friendship? Easy 10 points...?

What is your concept of friendship? What is your thought and philosophy about friendship?
I think that friendship is like when you've pi*sed in your pants, everyone can see it but only you can feel the warmth!
So what do you think?

Friendship is something everyone strives for, yet few attain a true and meaningful relationship. It is built upon layers  and groups comprising of your 'best friend', close friends, group members and 'friendly faces'. A best friend is supposedly the one who is your closest confident, the one you can turn to in dire circumstances. You wouldn't expect this person to cross you (although inevitibly they do ). Then there areur close friends, you tell these people (usually have 2) some of your secrets yet not the not significant in your life, A group member is similar, yet perhaps you dont share secrets, just friendly chitchat and laughs. A frierndly face is someone, well they're a friendly face someone you say hi to passing and ask how they are. These are all  different levels of friendship, each with different roles and aspects....
I'LL STOP WAFFLING NOW :p

I think friendship is a very easy relation. Probably the easiest of earth.
You don't have to provide and actually feed in contrast to being a parent.
You don't have to love unconditionally as one does in a love relationship. Love is complicated, friendship is not.

It is said if you laugh uncontrollably and don't care about how you look, you are probably with a friend.

You can be yourself and don't need to pretend anything, thats the biggest perk!

trust, a loyal person and some one that always listens and supports you even if your wrong
