Definition Esssay:Friendship.

Friendship  means: the condition of sharing a friendlly  relationship/ it is the feeling and behaviour that exist between friends.This definition is from Longman dictionary.But for me they are not good enough, this doesn`t transmit what friendship is; the first definition talks about the relationship  but doesn`t include why that relationship occurs, like , when you help a friend, the  relationship becomes stronger.The other definition is on the feeling and behavior among friends, but what is that feeling and behaviour? The feeling doesn´t appear easily and the behaviour it not allways good when a "friend" betrays you , he is not a really friend .There appears who is a good friend or the person who is with you, because of an interest .
My conclusion is that friendship is very good.
