What do you mean by "Best Friend"?

Sadly loneliness is my Best Friend! Anyway, to answer my expectations, A friend must be the one who cares his friend especially when he is in danger, problems, sick. other than that good towards him. never stab him at back, and never ever allow anybody to talk bad of his friend anywhere,etc,

A beat friend is a person that is much like yourself. You have a lot in common with this person. You can trust them with everything. They are there for you always in the good times as well as the bad times. They are the people you enjoy spending time with, going out doing things with.You can confide in them about any and all things, they will give you good advise at all times.They will tell you when you are on the wrong track.They will also praise you when you are doing well.They will chear you up when you are down.They always have your back.
