She says something that isn't really right but isn't really wrong. I'm not taking in their words any more, just their voices, trying to get a feel for whatever is going on between them. I'm imagining what it's like for them in this delicate situation, what I would say if it were me. She has that perfect upper-class accent, and she's using whatever upper-class tact that comes with it to navigate this. Style. They can't be together, but their voices are betraying them.

I'm in a crowded lift and a girl I've never met tells me she thinks she might love me.
The lift won't stop at any floor, and I can't talk in front of all these people.
