Hello. I think the urge to tell the people closes to us is that we get tired. Tired of be gaurded. Tired of being vague. Tired of limiting ourselves around them. About what you ask? About everything. Fashion, the clothes at red carpet, trends, shoes etc etc. we as a group tend to be more touchy feely and emotional. But when we have this facade up we tends to swallow those conversations.
My best guess is that that is why we want to tell the people closer to us. So we can honestly let our guard down. That is what we do with friends. Real friends. We are honest. We joke. We laugh. We cry. We gossip.
