Why do good friends tends to usually fight?

My best friend and I have fought countless times already and every fight made us better and closer friends. I agree that when you become so close to a person, you strip off the masks you have and all your friend sees is the real you. I do not put on a facade when I am with my best friend. I do not have to hide behind a mask of "good image, smiles" etc..when I am with her, she gets to see and feel the real me. Despite our differences and inadequacies, we still love each other and highly regard each others friendship. We may have fought a million times, it is because we do not agree on anything and everything but we always agree on one common idea, our love for each other and our friendship, which is the most important thing. After every fight we always feel that we have strip off yet another layer of ourselves and became more open and real with each other.

I think it's because when you get to a certain stage of friendship with somebody, you no longer have to put on a super-nice act and try your hardest to get them to really like you, because you are beyond that stage. Besides, it's human nature to have disagreements. No two people are EXACTLY the same, so a conflict of interests is bound to occur down the line. It doesn't mean you hate each other, it just means you don't agree with one another, which would be sort of creepy if you agreed with one another ALL THE TIME

I know best friends fight.... but you should really try and avoid them.... me and my best friends never fight... and we can't.... we just understand each other so well that there is no chance that we can fight on any matter.....if a person controls the relationship then it is healthy.... the person controlling should be understanding and give his partner the space she wants....

I think there is a psychological reason behind it. first of all there are conflicts in the two people. i meant that all the thoughts of two people cant be matched ever even if they are twin too. but some time we dont fight any cause we are cautious about our relations. but in friendship we are assured about relation that even if we fight we can get back after a day.

Fighting makes a relationship stronger even for friends. It really helps to sort each other out and understanding one another better. We have a good fight at least once a week. TATA.
