what does it mean to 'know someone' well?
does it mean that you can anticipate their every move, their line of thinking or reaction to any situation?
does it mean that you understand what they need?
or what they like, love, dislike, hate?

i'm not sure.
i'm not even sure you know me well enough.

does time change these factors?
do you end up 'knowing' a person through time?
