Best-Friend

I never got the "best friend" concept. How can someone unrelated by blood understand you in ways that you barely do yourself? Stick by you when you are in your worst moment? Offer help, expecting absolutely nothing in return? Is such a bond real, or just what people tell themselves?

I am at a loss sometimes to understand my thoughts, my emotions. If I don't even know myself thoroughly, how could I expect anybody else to? Yet the world idealizes this idea of a best friend. Is this reality, where friendships are made out to be flawless?

What really makes someone a "best friend"? Is it the person you like talking to the most? The one you spend the most time with? Or is it simply a title decided by circumstance, two people placed in the same environment, labeled as inseparable?

If you ask me, I may have few good friends, few more friends. But a "best friend," as the world defines it? No one. Maybe the problem is with me. Maybe I'm looking for something that doesn't exist.
