From your post i understand that I have been too metaphysical in mine.(Though I thought otherwise).

Okay, let us come to ground realities. You raised a valid question "How many instances does an average man/women spend time in a relationship without having expectations on each other in the world we live in ?" (and yeah, this question applies to Father - Kid,Teacher - Student etc as well)

Zero.Never,indeed. People ,or rather, AVERAGE PEOPLE, always have expectations from their partners.[ Note, I said average, not EXCEPTIONAL, I thought you were trying to reflect on the qualities of EXCEPTIONAL / GREAT /TRUE life partners when "you-stood-in- the-shoes-of-GOD-Himself" and came up with the anology of a doctor,with which I dont agree due to the elememt of egotism in the partner who is playing the role of the doctor.]

Anyways,coming to the Average people,as I said,and as you rightly pointed out,they do "expect".Now the questions worth asking are "How many expectations can a person have from their partners?", "what kind of expectations?" , "How many expectations can actually be met by normal,average people like themselves ?" "Is this expectation one way or Does the other partner also have a right to expect? what if the other partners expectations clash with the former's expectations?" What if one partners expectations are actually harmful for the other partners self,even though the former is well intentioned ( but he doesnt know it).who should comply? why?

These are all practical questions and they beg an answer.

let us take an example. A father wanted to be a doctor but due to circumstances he couldnt.He expects his son to be doctor.but the son yawns and sleeps off in biology class.His soul is interested in reflecting nature and capturing its essence in heartful poems.These are the facts of the situation.Solid hard core facts.Is the father wrong in his expectation? he only wanted his son to be successful in future, infact more successful than himself.Is the Son wrong in his so called disobedience?

More often than not, average people expect the other people to satisy their needs by proxy.Just as the parents in the example expected the revival of their lost dreams through their Son's life. An youngster might expect his parents to feed him even long after his college.A husband might flaunt his trophy-wife before his elite friends and earn social acceptance points.These examples which i used belong to one category of expectations which are widely seen in our society, we even have a name for this class,PARASITIC.Sadly few recognize the crime associated with them.Expecting other people to satisfy our needs , not acknowledging their potential individuality (though latent) and in the process crushing their spirit by imposing authority, inducing guilt,know-it-all-podium-preaching,better-than-thou-snubbing, emotional black mailing,physical abuse or other forms of psychological manipulation is criminal, if not downright evil.

If expectations roughly sound, "I am unhappy and its your duty to make happy" or "I want you to live my life and abide by my rules" or "You exist to make me look good " or on a serious note "I dont care if you are a tortoise, I expect you to scooba dive" we are walking rough terrain indeed.

Now if we limit ourselves to the wedlock relationship,which is between two mature individuals who are not physically dependant on each other for survival.The only valid expectation would be that of acceptance.Where there is no acceptance,how can there be love? how can I bare my soul and for a moment be my authentic self before my life partner when I know that she is going to crib about it? when she doesnt accept my whole being but only a part of me, that tiny part which exists only to serve me as a social face? How can I trust and let go? If I cant live fully even before the person who is most dear to me , how can I live at all? How can I ever be free of this prison of "expectations"?

This requires trust. Trust requires unconditional acceptance(from both partners) and this acceptance culminates in love. Interestingly,due to some strange reason beyond my comprehension,when one is loved ,more often than not,the beloved is intrinsically motivated to please the lover,and even more strangely,in the situations where there is a conflict of opinions,the beloved's disaggreement is pleasing to the lover.[for it is her best interest that he holds most dear in his heart,or so I presume.]

This is the best and PRACTICAL gift a person give to another, be it to a friend, a parent , a kid or a life partner : If you love, let go. [you will be glad you did]

PS : Just because something is "average" doesn't mean it is healthy ,normal and should be taken for granted or worse, followed !!! Average is just that. AVERAGE.
