friends...?

everyday we meet with people
we talk with them and have fun
we share each other's pain and sometimes we cry
so... what are the meaning of these things ?
does it mean that we are having friends ?
does every meeting counts as a friendship ?

in some cases...
people make friends because they have fun with their friends
it happens with many of my classmates
they regard everyone in the class as friends, since we all had fun together

in other cases...
people tend to make friends with another people they feel like 'clicking'
like, having some similarites
or they just can fit each other, as they feel so

another cases say different...
like in my case
the one i call friend is someone who cares about me
but is that really the cause ?
does any of the theories above can explain it accurately ?

so many books written on hundreds, even thousands pages
but no book can explain the thing to everyone

what i wanna say here is
everyone has different friends in their own life
nothing is wrong with the above explanations, though every single of them is different

when i feel that one is a friend, then he is one
when i don't feel so, then he is not one
it's simple
but you cannot force someone to be your friend, or ask him to call you a friend
i believe it's something that comes from deep down, our heart

for those who ar feeling lonely...
no one in this world deserves no friend
so seek out a friend for your soul
open your heart and learn to believe
i once lived in a dark world where i can see no light
and i really know, it's THAT bad, even worse
but anyone can overcome that world
and you can even be someone else's light ^^

for me, a friend is someone who cares truly about me
and i really love my friends ^^

so, what is a friend for you ?
