Hearing a loud exclamation, Jake whirled around to come face to face with a girl. Had his grandma not trained him to keep his face impassive when faced with a challenge, his jaw would have dropped open in surprise. As it was, he maintained a defensive position, eyes locked on the young woman in front of him for several moments before deciding to speak.

"Who are you? Are you the one who's been watching me? The one who was whistling?" Remember Jake, what Grandma always said. Don't rush into a fight. Ask questions first to ensure you have reason enough to engage in combat. He retained position, awaiting an answer.
