What does it mean to "be able to see through others, but not let others see through you"?

Question

i read this quote somewhere and found it interesting, but i don't quite understand what it means to "see through" people, etc. can someone explain how this can be done?

Answer 1

There are two parts to this quote.

1.) You can see more than just the 'outer layer' of a person. you are able to see into their personality and figure out who they really are.

2.) You do not like others to know the real you. You have more of a closed personality than an open one.

Answer 2

I think it means you can tell if a person is acting fake or has a hidden agenda even if they are putting on a "nice-guy" persona, but perfecting your own persona so that even if you are manipulating someone to get what you want they won't realize it.

Answer 3

Think of poker. It is clearly advantageous to be able to "read" your opponents and good for you to hide from being read BY them.
