Intimacy

Intimacy is often defined as arising from a close acquaintance, association, or familiarity. This definition would definitely describe the relationship I have with my sister, Catherine. We share just about everything that goes on in our lives and know each other like the back of our hands. We are so close, in fact, that rarely do we hear what another is feeling before we already know. We can tell each other's mood by the body …

…often include facts, opinions, and feelings. Lying does not come across good and it is rarely attempted by either of us. There are many reasons for this self-disclosure but it is mainly "just to get it off of our chest" or catharsis. A brother-sister relationship is definitely a unique one as evidenced here. Although it can reach some of the later and nastier stages, I don't see this as being the case in our relationship.
