Relationship... When this word struck in mind, our mind goes in flash-back and changes our current mood. It can make our mood happy, upset or sad.
Relationship can be of many kinds; a relation becomes only when there are 2 or more person involved. Friendship, Parent-Child, Siblings, Lover, Husband-Wife, Colleagues, Employer-Employee, and many more. These meaningful words were given by humans. We say "He is my friend", "She is my Love", "they are my parents", "my manager is good", "my reportee isn't working", and others; but do we really know what is behind every relation?
Every relationship starts with 2 strangers, then they give the name to relation. How do they give name? There are some relations which are pre-defined like parents, brother, sister, manager, employee. In every relation it is the amount of bonding you share with the stranger.
