What do I think about Backstabbing and Gossiping?

Backstabbing and gossiping- in Buddhism teaching is not allow. But I some sort of have some disagreement in it. Its not that I'm bad to say that, it because after all we are all human being. And sometime we also may say something bad about our family to our close friend. And I think this is just letting out of our feeling and not totally that we are a bad person. As long as we don't backstabbing and gossiping often. And I think its alright at times if we need to. To the most honest saying, in reality we simply can't avoid in backstabbing and gossiping . I know I shouldn't have talk in this way but I just letting out my words.
