Because, you know, it's a thing.
Entanglement is like when you're trying to get a cat to take a selfie, but they just won't cooperate.
They're all like, "I'm over here, human! Stop bothering me! I'm trying to contemplate the meaning of life."
But then, just when you think you've got the shot, they'll suddenly be over there, pouncing on a laser pointer.
That's entanglement, folks. It's like the cat is connected to you, but not really.
