reality is in the perception

so, i'm going to try to put together some thoughts, lets see how it goes.

so, we often talk about reality, but it quickly diverges into this metaphysical conversation referencing people like Descartes, Locke, etc... what i want to talk about is our perceptions...

first off, what's real almost doesn't matter, it's what u perceive... when someone says something, it's not the words u actually use, but their interpretation of those words along with the tone, for example:
Person A: "Thank you"
Person B: "Your welcome"
simple, right? well, lets assume both persons are ernest... that's one interpretation, but lets assume Person A is sarcastic, Person B could not have noticed and be earnestly replying, or they could be replying in sarcasm or any other gamut of emotions... now, lets think that Person A is earnest, etc, do u see what i mean?

now, this is such a basic little interpretation, but sometimes people change their own reality. they make a tough decision. now, the normal reaction is to begin justifying that decision as often as they can. it's really quite the phenomenon, even amazing to watch! they begin to perceive things pre-decision in light of the decision. i usually think of this as "they lie to themselves", but it's not that, i'm not sure if i could call it lying, they're simply changing their perceptions in order to be more comfortable with their decision. i cannot blame them for that, i am the same way... so...

what i'm trying to say, is, at some point in your life, your perception of the past will be different than what actually happened, and very different from others who were involved, don't be alarmed, it's natural, but be aware of your own tendency to change your perceptions of things that were and it will help your things that are and things that might be.
