You would, but you can’t.

Doing your best to stand your ground (mentally & physically) despite the extremely-rare situation, you keep your feet firmly planted where they are.

“I… I’m sorry I turned you down,” you say to Cheryl’s seemingly-departing backside.

“I understand,” she replies, turning to face you again as she laughs lightly. “Sure, something with me may be once-in-a-lifetime, but friends will only be forever if they’re not mad at you for cancelling plans you’d made with them. Now, let’s dance, birthday boy!!’

“I…,” you say again. “I would… REALLY, I would… But I can’t.”

“I don’t believe that!” Cheryl says.

“If you can’t dance at all, how did you end up getting led here by 2 girls looking & moving the way THEY did?!”, she asks, gesturing towards the lift as she references the girls that had left you on this floor.

“Be the birthday boy,” you explain, “& you can never know what sort of things will come to you… Besides, I was more standing there while they danced ON me.”

“I guess that will explain it,” she finally says, though you notice she’s shaking her head in disbelief. “Let’s go,” she adds, still sounding disappointed as she heads back towards the lift you arrived there from.
