Putting aside the clear satire tone, the song tries to put logically one of the things that most people have such a hard time thinking objectively about; love. We all have those who are close and dear to us and it can be difficult to imagine ourselves without them. Yet the world is filled with unexpected events so before assuming that we have found our one and only love, we should look at it logically.
With over 7 billion people in the world and possibility of travel, if your boyfriend or girlfriend left you it is unlikely that you would not be able to meet someone, unless you were to lock yourself in your bedroom and cry to the end of time.
“But of the 9.999 hundred thousand other loves
Statistically, some of them would be equally nice”
If one does not feel as close to a new partner as to the last one, that may change over time as you increase memories and experiences with the new person.
“Love is nothing to do with destined perfection
The connection is strengthened, the affection simply grows over time”
As well as with many other things it also has to do with luck, with the number of events and decisions that led to meeting that person at a point in time in which a relationship could form.
“I’m not undervaluing what we’ve got when I say
That given the role chaos inevitably plays in the inherently flawed notion of “fate”
It’s obtuse to deduce that I’ve found my soulmate at the age of seventeen”
Yet, given that nothing or barely anything can be given to granted, there isn’t something that can give 100% insurance that we will all find someone to fall in love with, even with all the billions of people on this planet. We can however say that it is “probable” that if your high school sweetheart breaks up with you, that will not be your last relationship.
