Confused...

Some times i wonder, why the hell we met. Is it destiny which brought us together or something else.
Yes i m talking to you my friend, yes you, can you tell me the answer.
Oh! please give me an answer.
I would be glad to know what u say, otherwise I would be at dismay.


Friend 1:- Its destiny which brought us together.
Friend 2:- I don't know.
Friend 3:- Because i needed you and you needed me.
Friend 4:- It could be because we are in the same class


the best answer may be the 3rd one, but it is from the one i never expected from.
so what do i call the other three friends as,
i cant differentiate because the other 3 are supposed to be my closest friends
and the one gave the perfect answer is just a friend.
I am still confused........
