Friendship, help me out here...

This concept of 'friendship'. People use this word a lot.

A good definition for you:

Friendship is a term used to denote co-operative and supportive behavior between two or more humans.

Who decides the terms of a friendship?
The strongest person in it or the person who's better at manipulating?

Now, its in the human nature (hell I suppose an animals nature too) to be curious, nosy, sometimes even rude and ignorant (yeah, some of these probably don't count towards animals) but, if someone has a close group of friends why would you test the friendship to the extent of make or break?

I've realized that aside from having to travel a lot since being at home for this year, I also get less gossip. This is good. It means I almost stay neutral, and even avoid some bickering.

Me, I argue a little bit with my friends, about the film we'll see, or the stupid choices they make (or the stupid choices I make), but I never decide to grab a small problem and think to myself; "Well, I've got this air pump here, lets shove it into the problem and use the pump until it gets to about 49 times its actual size"... Question to the few people who do do this Why? Somethings are not worth it...

Friendship, yeah. The definition sometimes needs a bit of tweaking.
E.g: 'I'm only your friend if' Or 'I'm your friend but' - Now this seems like a get out clause to me. For a second, just think, averagely (I'm guessing) people on this site have what 100-150 'friends' ? What about you? How many are actual friends (using your own definition) and how many are actually colleges, or people you've only met a handful of times who you probably wouldn't waste your time on even if they offered to buy you, say, a house?

I consider a friendship to be where the majority of the time you don't bitch about, moan about, argue with, feel anger towards the person/people. Where actually you have no negative drama within the friendship, just a good time.

So to get back to my point what is your definition of friendship, I'm intrigued. The study of friendship, yeah, that can be my PhD.
