That is a Disney quote then

Dear future hubster,

do you know those very motivational and supposedly deep quotes saying "If you find that special someone, don't let them go", or something equally patronizing?

Next time you see one, or somebody shoves one in your face, feel free to call their bluff. Because what they're saying is utter bullshit. 

Newsflash, dear future hubster: you don't get to choose who gets away. You don't get to choose who sticks around. There's no such thing as not letting go. If they want to go, they will, and you may get to choose the amount of grace you handle it with, or the amount of disgrace you want to throw at them, but you have no say in the 'what', just the 'how'. 

Best you can do is to keep being that cool and warm and bright and somber and simple and complex and serious and ridiculous person they chose to be with in the first place, and hope that they keep choosing to do so.

Remember who you are, I guess.
