Let's get realistic about love.
For this exercise, we will make certain broad assumptions, discounting exceptions and outliers. We will try to figure what's happening statistically when two people fall in love. We will also place our exercise in an Indian social and cultural context.
Let's start with the potential "universe" of people one can possibly fall in love with. We will start with the total population, and reduce for mutually exclusive groups. India has 1.2 billion people. ~50% for the opposite sex -> 600 million. India's median age is 27 years (50% population less than 27 years of age) . For this exercise, assuming that one intends to get married in the age range of 24-32, an 8-year span (our math won't vary much if we increase this window on either side by a few extra years, there is a bulge below this range), we are down to ~80 million.
It gets a little tricky from here. Remove for some semblance of economic backgrounds and we are down to ~8 million (80 lakh). Now from this, remove for religion & caste preferences (I am looking at you Brahmins), dietary preferences (no onion no garlic anyone?), height & weight preferences (taar bijli se lambe humaare piya), complexion preferences (it's only fair, right? Lovely), educational preferences, language barriers and north Indian and south Indian and Gujju and Mallu and Kashmiri and Jat preferences. And so far we haven't removed for people already married or in love with someone else who is not you. And after you have removed for all of the above, you need to be with a person with whom when you spend time, your emotional response to them lies between "surreal" and "I can stand this person" on a scale of butterflies, and the other person's emotional response also lies somewhere in the same ballpark. And whoever you are left with, you haven't even begun to find him/her yet. Given your life experiences of school, college, workplace, pubs, bars, travels, tinder and what not, and the count of people you potentially meet through these life experiences, what are the fuckin' odds.
I had always believed that the concept of "the one" does not hold. But given the odds, and given that there exists atleast "a" one, you are probably better off with a the. Two people falling in love with each other is a statistical miracle.
[from Watchmen] Miracles. Events with astronomical odds of occurring, like oxygen turning into gold. I've longed to witness such an event...; ...and out of that contradiction, against unfathomable odds, it's you - only you - that emerged. To distill so specific a form, from all that chaos. It's like turning air into gold. A miracle.
I hear "everything is great, but I am not so sure" ever so often that it's fuckin' unbelievable. I don't understand why anyone in their right mind would break up. You met someone and liked, and they liked you back, and you loved each other's company, and then you eventually started driving each other crazy and "it didn't work out"?! Huh?
For people who are single still, I feel sorry for you. The odds are stacked against you and there is little hope for you (lol). Live, is all, and maybe, just maybe lightning will strike (in this case, twice). And for people who are married or with someone and in love, go hug your Significant Other really hard right now right this moment, take a good look at them, smile, hold their hands, and know that they are your one in a million. You have witnessed a miracle.
