friendship requires no explanation... but...

Friend could be either a male or a female.. so i am just removing she or he references and naming the person as Z.. no gender biasing.
Z is definitely not my brother/sister nor my boyfriend/girlfriend; Friend, close to heart. When i needed Z's help, Z was always there. Whenever i want to say some secret, Z could be helpful. This Z is so good, that i will ask Z to be in my dowry kit :) ..hey Z no offense please. I believe everyone should have one like Z. How am i gonna repay all these?.. Well, the fact is Z is not expecting me to repay all this in the same way as Z did to me, but i believe Z will expect me to help Z whenever i could.
This is a recent observation that i made in my life. I have two friends say 0 and 1. They were/are really close friends (u wud know why i made it "were/are" in the sentence after u read d post). 0 met with a tragedy in its life and wanted 1 to help it to get through ( emotional support) 0 always asked rest of its friends to ask 1 to come and meet 0. But 1 acted as though it dint know 0 as closely as it did. 1 dint come to support 0 as much as 0 expected..... my observation could be incomplete, but i m judgmental here from this observation. 1 could hav atleast acted a bit more concerned about 0. that's my view. But it stirs me up, as i ( i would say a more distant friend) had to push 1 to see 0. If i were 0, definitely i would have given a punch on 1's nose and then requested 1 to be a better friend ( though i would never let 1 go away from my friends circle)
