Eerie

“There are people whose eyes you must avoid, whose attention you must not draw to yourself.
They are strange, parasitic creatures, lost souls seeking to stretch across the abyss and make fatal contact with the warm, constant flow of humanity. They live in pain, and exist only to visit that pain on others.
A random glance, the momentary lingering of a look, is enough to give them the excuse that they seek. Sometimes, it is better to keep your eyes on the gutter for the fear that, by looking up, you might catch a glimpse of them, black shapes against the sun, and be blinded forever.”
― John Connolly
