This article is to encourage an healthy friendship in our society. Many a times people mistake best friendship to exist only with the opposite sex which is not so. A best friend can be of same sex provided you have your boundaries to avoid intimacy.
Who is a Best friend? This is someone who is your indirect replica. This is some one you can actually model and such a person becomes your prototype.
A person who can stand in your absence and defend you at all times despite the critics about you.
A person who is compatible to you. While others spread rumours and ask WHY HIM/HER? You are like HE/SHE is the BEST you can think of.
A typical instance is the story of David and Jonathan (i. e Saul's son) in the Bible. 
Today I take the single honor of encouraging an healthy friendship in our society........
