I think, at the core of it, most of us want to know and be known. Not in the sense of becoming famous, but for someone to see who we are -- the person we are inside. At the same time, we're afraid that if others were to see that person, they wouldn't like him or her, because we're all too aware of the myriad flaws and weaknesses we have, the ones we take pains to conceal and go to great lengths to ensure nobody will ever know of.
It's a catch-22 kind of situation. But it's why we're always reaching out for love, because we know only love can forgive the ugliness that resides within us... and more than forgive: it embraces the whole person, imperfections and all.
