The best way to get a closure in a relationship that you are holding on to with fading hope is to ask that person, “On a scale of 1 to 100, is there a 1% chance that you might fall for me sometime in the future?”
If that person says, “Less than 1%”, the inveterate optimists among you might think you are still in business, singing under your breath, “Yahan kal kya ho kisne jaana.”
If the person says, “0%”, you have to be delusional to still think that something can be salvaged.
But, if the person says, “Minus 50%”, then if you think, “Well, thank God, at least she did not say Minus 100%, so…”, I would suggest you start looking to book an appointment with a local psychiatrist.
