how long does is take to get to know a person - Reyep
Sometimes a movement tells everything, sometimes you live in the same house for years and you can't recognize it.

There is no time for this job, besides the fact that people you think you know well can turn bad over time.
one moment maybe even less. if you need longer time you will not be able to recognise it no matter how much time you spend.

People change, everything is momentary. The stronger your ability to follow the moment, freeing yourself from the burden of the past and the anxiety of the future, the stronger your ability to get to know people.
