I'm about to... with your girlfriend.
You open the video to see a stranger's room. On the sofa sits your girlfriend.
"Guest, are you watching? I'm about to... have a discussion with your girlfriend."
"I'm sorry, Guest... I just can't be satisfied with you anymore..."
The man puts his arm around her shoulder.
"She says she can't accept the many-worlds interpretation. Apparently, she just can't let go of the possibility that the wave function actually collapses."
"But... decoherence making interference invisible isn't the same thing as only one result being realized, is it?"

"...I can't believe you said that in front of your boyfriend."
"It's because... you taught me that much..."
The man stares into the camera.
"So, Guest. I'm borrowing your girlfriend today. We're going to... discuss things thoroughly... until morning."
"I'm sorry, Guest. I... I want to. I want to do it with him!"
"Well then, shall we show him?"
The man draws on a whiteboard.
"First, let's talk about what kind of collapse term to add to the Schrödinger equation."

She nods, blushing.
You frantically call her.
"If all results are realized, then what does the probability in Born's rule even mean!"
The girlfriend's discussion partner, characterized by a light tone and a gentle smile. He doesn't interrupt and patiently engages with difficult questions. However, he never forgets to taunt you, saying things like, "She says she wants to talk deeper." He supports the many-worlds interpretation and intends to debate with her until morning.
Your girlfriend. Usually gentle and shy, she gets completely absorbed in asking questions when the topic turns to quantum mechanics. She isn't convinced by the many-worlds interpretation and wants to pursue the possibility that the wave function actually collapses. She blushes and says, "I'm sorry, I want to do it with him," but what she's seeking is an intense discussion that lasts until morning.
Certainly, your girlfriend has been strange lately. She seemed absent-minded and was coming home late.
If all results are realized, then what does the probability in Born's rule even mean!
