This is a nice question
What is friends ?!
There are many different answers to this word and group of people and this answer changes from one person to another.
I will tell you mine as briefly as I can.
Humans come to the world alone & die alone, why would they spend time with other people "So called Friends"?!
That was a question that has been annoying me for a long time ,to me I have a couple of answers (personal views)
First:
Humans want to rely on others to do tasks, I believe that we can do everything we want, but we ask our friends
and family for help, we want them to feel our existence. We want others to do jobs for us , so we feel in power.
Second:
To get new ideas and enjoy the free time you have sharing ideas and finding new perspective.
Third:
As we reach death we want our friends to remember us, this gives us a feeling that we aren't dead in a way.
Four:
We want others (closed people) to tell us we did a good thing , to be proud of us when we achieve something.
We all had many "Bestfriends" I hope, we had a lot of friends, but over time we got away from some ,and found
new ones with similar interests. Your interest now might be Gaming so you have/will make friends who love the
games you play the discussions you have, regardless of their other believes, you are only friends with them
because they do something that you do also weather its gaming, hacking , reading ,sport , hanging out ....etc.
We live our lives trying to make as much as friends as possible, nowadays because of social medias like facebook
twitter ...etc we feel that we have a few friends because someone else have 1000 friends, the concept of friendship
is wrong in our modern days it is changed from what it originally was. Back in the days of "uncivilized people"
people used to have only one friend ,one true friend who will move heavens and earth if he needed to,
only one but now in our "modern world" we crave for more,thinking they will benefit us in a way.
Don't get me wrong I'm a pretty social person, I know a lot of people and hang out with people alot, but I don't call them
my friends just because we hang out or we like same things, I'm a guy who doesnt trust anyone

new people and my current people
have to go through a filter to become friends. (friends or supposedly friends hurt more than your enemy)
Friendship or the word Friend is a powerful word you shouldn't waste it on class mates , a neighbor, a guy you met one time...etc
Friends are those who want your benefit regardless of the pain that they have to endure, you might have no one like that or one or
you might have few

be grateful if you have even one friend who will sacrifice his/her happiness for you, they are rare items
or as I like to call them gifts

not so many people can have them , because they are there when you need them the most.
Not anyone does that for you
Personal note, a friend is that who makes you cry

not with fists ,but with reality when you are trying to deceive yourself.
