As Aya walked down the hall, she spotted another girl who was around her age coming from the opposite direction. She walked up to her and asked, "Excuse me, but do you know of anyplace where one could get some fresh air around here?" She didn't know the other girl, nor how long she'd been there. All she wanted to know was if she could breathe air that had not been cycled through the vents.
