Friendship is a term used to denote co-operative and supportive behaviour between two or more social entities. This article focuses on the notion specific to interpersonal relationships. In this sense, the term connotes a relationship which involves mutual knowledge, esteem, and affection. Friends will welcome each other's company and exhibit loyalty towards each other, often to the point of altruism. Their tastes will usually be similar and may converge, and they will share enjoyable activities. They will also engage in mutually helping behavior, such as exchange of advice and the sharing of hardship. A friend is someone who may often demonstrate reciprocating and reflective behaviors. Yet for many, friendship is nothing more than the trust that someone or something will not harm them.
Value that is found in friendships is often the result of a friend demonstrating on a consistent basis:
the tendency to desire what is best for each other.
sympathy and empathy.
honesty, perhaps in situations where it may be difficult for others to speak the truth.
mutual understanding.
It is often considered that a true friend is capable of deep feelings, which may be unexpressible, except in times of great trouble, when they come to one's aid.
In a comparison of personal relationships, friendship is considered to be closer than acquaintanceship, although there is a range of degrees of intimacy in both friendships and acquaintances. For many people, friendship and acquaintanceship lie along the same continuum.
The principal disciplines studying friendship are sociology, anthropology and zoology. Various theories of friendship have been proposed, among which are social psychology, social exchange theory, equity theory, relational dialectics, and attachment styles
Etymology
The English word is of Germanic origin, and related to the Old English fréond with the same meaning, and the Old Teutonic frijôjan, to love.
History
Friendship is considered one of the central human experiences, and has been sanctified by all major religions. The Greco-Roman had, as a paramount example, the friendship of Orestes and Pylades. The Abrahamic faiths have the story of David and Jonathan. The Christian Gospels state that Jesus Christ declared, "No one has greater love than this, to lay down one's life for one's friends."(John 15:13)
In philosophy, Aristotle is perhaps best known for his discussion (in the Nicomachean Ethics) of philia, which is usually (somewhat misleadingly) translated as "friendship", and certainly included friendship, though is a much broader concept.
Cultural variations
A group of friends consists of two or more people who are in a mutually pleasing relationship engendering a sentiment of camaraderie, exclusivity and mutual trust. There are varying degrees of "closeness" between friends. Hence, some people choose to differentiate and categorize friendships based on this sentiment.
Friendship contrasted with comradeship
Friendship can be mistaken for comradeship. Comradeship is the feeling of affinity that draws people together in time of war or when people have a mutual enemy or even a common goal. Former New York Times war correspondent Chris Hedges wrote: "We feel in wartime comradeship. We confuse this with friendship, with love. There are those, who will insist that the comradeship of war is love — the exotic glow that makes us in war feel as one people, one entity, is real, but this is part of war's intoxication. As this feeling dissipated in the weeks after the attack, there was a kind of nostalgia for its warm glow and wartime always brings with it this comradeship, which is the opposite of friendship. Friends are predetermined; friendship takes place between men and women who possess an intellectual and emotional affinity for each other. But comradeship – that ecstatic bliss that comes with belonging to the crowd in wartime – is within our reach. We can all have comrades." As a war ends, or a common enemy recedes, comrades return to being strangers, who lack friendship and have little in common.
