A person i know told me a story the other day about an interesting cafeteria worker at HER college. Unlike my example, this worker does indeed have a disability, a mental disability. But all she does is scoop food and clean, so she sticks around. That's all she does... yeah, and masturbate in the girl's bathroom stall with the door open during her lunch break every day.
There's been several sightings, traumatizes, and testimonies given... but the behavior continues.
So again, I propose for her to sport a representation of her acceptance of her oddity. I'd tell you my idea for her pin or what have you, but i think its best left up to the imagination.
