what you consider shows friendship between two person ???

Well to me, friendship is based on trust, platonic love, loyalty, and similar interests. So basically if you and someone else can get along for a long time, can trust each other with secrets (depending on how far along your friendship is), wouldn't dare talk smack behind each other's backs, and you have a lot of things you both like, that's the perfect equation of friendship. Of course there are other exceptions where people are friends, but do not get along after a certain amount of time. . .or on certain things. I do not think there is such a thing as a perfect friendship. Friendships can be very fragile, and the amount of trust people have for each other will determine whether or not it will break or last for a long time. That is what I think of when I think of friendships.
