Perception

Truth and honesty is homeless creatures in a world where the human species find their existence so alien.

What a human wants can never really be answered because the similarity of the brain the structure is relatively (not wholly) irrelevant psychologically to the mind's way of processing information.

The difference between knowing someone and perceiving them to be someone is that the former follows the latter.

Perception? Funny because an error of judgment, an act of prejudice, a set of preconceived notions can drastically impact your perception towards someone; and the level of emotional intensity, you have in your mind towards them influences and renews your concept of perception. 

Subconsciously at least, your perception and its meaning changes with each experience, no matter how big or small.
