bilkul b zaroori nai hota... i gave a explanation that the level of relation which we share is LIKE A BROTHER n SISTER
to be honest i hate this label as well... thats y i said "HE IS MY FRIEND" who is "LIKE" a brother to me!!!!!!
i m agree with i got friend as well ,i m married and he is gonna married at the end of the year but i never consider him my brother but now i have to call his fiance bhabi,and he calls my husbund bhai,
