Sight leaving my one resthome job the other night:

A (laid back) (older) (black) woman in a wheelchair in sunglasses and with a big scarf wrapped all around her head and neck and shoulders, just hanging outside the liquor store as it's closing, singing "O Holy Night" at the top of her lungs to the pretty empty street.

And, she didn't seem insane, just bored, and maybe doing things in her own style.
