What is Best Friend and Who are they?

It may not easy to define what best friend really are. Whatever we may say, we can define best friend as a person who means a lot to us. Specifically, best friend is the one we can rely on when we are suffering most. He/She is there for us when we need someone to talk to, and helps us overcome adversity. He/She will back us up all the time, but he/she will not judge us for the stupid things we may do or say, because he/she knows best how to make us feel better. No matter who satnds against us, even if the whole world become our enemy, a best friend would never leave us behind for even one moment. All in all, regardless of how many friends we have, or, how many cycles we have gone through, there's one thing we are always looking for and that is the one we call "Best Friend".
