Friendship is a kind of relationship that many accompany you all your life. The relationship with your parents will be put to an end with their passing away. You have an association with your colleagues, but it is always changing, because one day, one or another colleague may disappear suddenly out of your routine by changing jobs.

Only friendship can be everlasting an steady. You may have friends as early as infancy. No matter whether you are married or not, no matter where you live and work, your friends are your friends. It is not based on bloodline. It is rooted in the desires and feelings derived from social experiences. It relies on your intention

 In my opinion, that is the social nature of friendship. Making friends is to meet people's varying needs. People have all kinds of desires. To achieve progress, you make friends with those who surpass you. To enjoy freedom, equality an mutual respect, you make friends with those who are of equal stature with you.
