Knowing
To me, knowing someone or something is a perception. A perception is entangled by different frames. These frames are like frame of time, frame of reference, frame of context etc. Knowing the whole is impossible and can not be attained by anybody. Now what I know is perfectly all right with my frame of reference and at the same time it could be contradictory with some others knowing with its own frame of reference. So somebody else knowing me is perfectly false case.
Now let's check if I know myself very well or not? Again what I know is what is seen by my ego. And accordingly I make my perception. Now my ego will only show the right things/virtues (which it feels right) to my self. It will ignore the bad things/properties (which it feels bad). So again the knowing of self will be through the eyes of ego and it can not be perfect always. The above frame of time and context also are applicable here.
So in all knowing completely someone by anyone is impossible. A mere possibility of knowing someone by anyone is only captured within the frame of reference, time and context. But again it is the perception and not the true complete cognition.
