What does it mean when a girl stares at you with her mouth opened?

Early today, at Jewel-Osco. A girl was pushing her shopping cart, and staring at me behind in front of me with her mouth opened.

It sounds like she was on fly-catching duty.

She had a cold and she couldn't breathe out of her nose because it was stuffed up

She might have her nose broken.

She's mesmerized by you.
