Friends or Companions

Companionship is only the matrix of Friendship. It is often called Friendship, and many people when they speak of their "friends" mean only their companions.

Friendship arises out of mere Companionship when two or more of the companions discover that they have in common some insight or interest or even taste which the others do not share and which, till that moment, each believed to be his own unique treasure (or burden).
