With a deeper thought I feel these three words are so entangled in to each other. Change in Priorities for some reason increases expectation from them, and increased expectation increase the chance of disappointments. This is so simple yet so complicated. We as humans change our priorities for others at some point in time and expect something in return (not as an return favour necessarily), and often are disappointed not to see that same change in priorities reciprocated or even other expectation which are not met with. Of which the other person is not even aware of. How appropriate is it to have these expectations? or for that matter lets address the root cause, how appropriate is it to shift your priorities? Well another angle to it, does the person in front know you made the change for them? If yes and then did not reciprocate, you learned you lesson and move on. but if they dont know then, how fare is it to them, for you to be angry with them?
Well thats a rather complicated set of questions. With no answer! As human you will make changes to your priorities (for various reasons I would like to keep out of this discussion), and then have an expectation of reciprocation from the other person, failing which (knowingly or unknowingly) you will hold grudges against them. Now if taken from the other person’s perspective it is unfair on them, but if seen from your perspective it is not all that wrong. So is the perspective a problem? Well another question with no clear answer. There can not be one suits all solution to all these things we have talked about, for they are so much dependent on the perspective from which you look at it.
Every one will have different perspective about you and others. It is that perspective that they use to look at you and set priorities for you in their life, so you have no control over it, and why scratch your brain on something that is out of your control…
Moral of the story is: Life is hard, Mintrox!!!
