"Dayh!" Flo explained as her balance left her and she had to extend a foot to stop herself from completely falling over. She faded into being, the exercise ball no longer alone, but a throne to an oddly-shaped, awkward looking young woman in gray sweatpants and a blue T-shirt with the Superman logo on it. (With a tear under one arm, but as long as she didn't raise her arms she was fine.)
Some of her hair had escaped her sloppy ponytail, so Flo had to brush it out of her face as she tried to look behind her, since a force had been applied, and where there was a force there was a source to the force. Unfortunately, despite being a round thing, the rubber of the exercise ball made it hard for her to turn around on, so it took Flo an awkward moment or two to see where the force had come from.
Her first thought was 'freckles.' Her second thought was 'Pretty Girl' (in capital letters.) Her third thought was the one she decided to start with. "Did you just kick the side of my ball?" she asked, looking all of the way up at the Pretty Girl with freckles. Normally, she would not have to look up so much, but since Flo was sitting it was quite a distance.
Flo narrowed her eyes at her, not out of anger, but because her little wheels were turning. "There is something unusual about you," she said, pointing quite rudely up at her. "I don't think it's an unpleasant unusual quality, but something about you gives me the impression of not being like other people. Aside, of course, from the fact you are here, which confirms you aren't like other people. Nor am I, you basically have to be unusual to make it in the elevator. Which makes even the elevator itself unusual, isn't that funny? Are you glowing?"
