There will be moments when you think you know a person, really know her. You think you understand how this person thinks, how she functions, how she reacts. But in those moments, I advise you to stop. The minute you think you know, you cage this person within your own limited perception. She is not who you think she is. She will simply be a creation of your own thoughts. She is no longer free to be who she is but limited to what you think you know.
A person is a myriad of thoughts, a million little pieces coming together to compile the atoms and cells and organs that make up who she is, at her essence, at her core. How could you possibly think that she can be contained?
