Sarah's eyes shoot upnto glare at you...

"And what the hell do you think you're doing in here?" She asks you quickly, the anger in her voice plain...

Sarah's glare doesn't flinch...

"Are you just going to stand there you creep?" She asks, her eyes flicking to the door, as if telling you to leave while you still can...
