Seeing Other People

I always wonder what other people are thinking about me and always wish that I could read minds.
It's so difficult to get into someone's mind and try to know the psyche of the person; yet easy to classify them in broad catagories.Certain kind of people change for that moment when only around certain kind of people and then they are back to the way they were around you. They will act all sophisticated while with the 'sophisticated' group of people, very cool and chilled out while in that certain group; etc. Does that mean faking? or its simply being smart to gel with everyone. And in that process more often than not they themselves forget who they are, Everyone has a different 'face' for different sets of people and situations. There is nothing really constant about any of them. Nobody can claim to know eveyrthing about someone, its just humanly impossible; we can know only what we are told and what we see; and what we see is only what the other person wants us to see.
Then there is always a difference between what one says and does, its so easy to tell someone how to behave in certain situations and what to do; but when it comes to their ownself everything is conveniently forgotten that too supported with a justifiable reason; which again is sometimes just a game of words.
People are what they are as they want to be seen and as we want to see them.
Its all a web; does it mean everyone is just putting up a certain face; and what I know of them is all just a certain dimension of them?

Maybe ; maybe not.
