The two of you take the elevator to the lobby, then the parking elevator to the lower levels. Her heels click on the concrete of the parking lot as she walks, the sound echoing in the largely empty space.

"I always think underground parking lots are a bit spooky," she says. "Like someone's hiding somewhere, waiting to jump out and grab me." She gives a short giggle.

"This is my car. It sounds like you might enjoy that, being grabbed." You open the passenger door for her and she turns and looks up at you, as if gathering her courage.

"I'd like it if it were you, sir. If it were you grabbing me." She leans towards you, her lips parted slightly, her eyes half lidded.
