Just emagine a life where there is no one to shre your good or bad moments. You are the only walker of this long path without any company. There are so many people wandering around you but none of yours. No one to walk with you.
But the life provide friends to your path as your relative or as unknown person. Friend is not a person who is living with you, eatting with you,sleeping with you but the one who is with you when you are alone.
