You

You may be what I think you are
but
that is not all that is there to you.
There is a lot more that I can never know.

I may try to box you, simplify you
but that will just be what it is and nothing more- my perception of you.

You are much more complex than I can ever imagine.

Myself

Anyone else cannot know everything about me, however hard I and/or they try.
Can I tell everything about myself to someone else? No. And this is not because I don't want to, it is because I cannot even if I want to, with all my heart.

This is an example of the limitation of communication, of language.
Or is it?

Don't I have to understand/know myself to be able to explain myself to someone else?
What does understanding/knowing mean?
Even if I understand myself will I be able to express it to others?

Knowing myself is not like finding an equation/model that governs me, that predicts my behavior. I don't know what knowing is. I am not even sure if I can know. I seem to be committing the mistake of talking of 'knowing' in the limited sense that science talks about. I think there is much more to knowing than equations and proofs and classifications, predictions, models and probabilities.
