Interpersonal Relationships.

I've began contemplating about interpersonal relationships and that wall we put up between our true identity and what we show others.
Even in our most genuine, trusting, reciprocal relationships do they ever see the 100% raw us? Can they ever see past the visage into our deepest darkest soul? Even in truth, it's not a lie if you don't say it. I know there are things in my head, things about myself, about other people that will never come into creation with words. There are even times when exposing too much of your thinking can be problematic.
Another question is, by doing this are we protecting ourselves or the people around us? I guess in some respects, depending on the circumstances, it can be either.
Right now however, it's that sense of closeness and that wall between us and others that intrigues me; Depending on the type of relationship, the circumstances around meeting, the time you've spent ,and the feeling you have towards them some people in this world will never see us more than "Hello, Thank you, have a nice day." and others will be let in to see our moments of great strength and also, great weakness. They may be impressed and envious of the person we show due to a certain situation. Or, lose total respect. It's funny in a way, because it's not always a true representation of our true inner workings but only at how good we are at molding the self we bring into being to show others.
There are some of us who hold that wall up for too long and too strong to let anyone get to know them any more than a superficial being, and those that come off in an unfavourable light for letting the wall down too soon and exposing too much. It's a certain tact to build meaningful interpersonal relationships, to assess your opponent and execute the right amount of yourself (or depending on the person, a total lie) to bring that person closer to you.
I wonder, if our thoughts were transparent, and we knew everything about everyone we came in contact with, how many of us would keep that bond?
Would you gain or lose friends if there was nothing to hide?
