There once was a spider warrior by the name of Theodoseus the Great. For years he feasted on the remains of mosquito families and dragonfly babies he captured in his great webs. When humans came into his territory he creeped into their quarters, only to force them out minutes after his arrival.
His reign of terror spread from the jungles of Vietnam, to the countryside villages, and even as far as the metropolitan area. For Theodoseus, every human he encountered screamed and ran in the opposite direction.
One night-- as Theodoseus preferred to travel by nighttime so as to avoid being potentially stomped on by human feet, he stumbled upon a gated community. Oh, this will be great, he thought to himself, a bunch of sleeping people I can scare awake...then I'll take over the whole building to myself and get to work on creating an empire. So he crawled through the somewhat rusted white bars, past the sign reading Hoa An Center.
Once he reached the white tiled stairs, he decided to clear out the first floor of rooms first. Creeping through a window, he mounted himself right next to the bathroom door. Surely an unsuspecting human would stumble towards the bathroom in the middle of the night and then shout out upon finding Theodoseus. So he sat, and waited-- not even bothering to spin a web to settle down. This would all be his soon enough, no need to rush.
Around 5:00 am, Theodoseus heard an alarm clock ring, and a shaded image moved towards the bathroom. No flashlight. Perfect.
The human entered the bathroom, did their business, and as they began to wash their hands their eyes must have adjusted. Sitting there perfectly still next to the mirror, Theodoseus heard the scream. But it was not nearly as loud as he expected. They're not terrified? Merely taken back? This had never happened before. The human left, probably to tell the others they needed to get out because of this great spider. But instead, one by one, the humans came out to do their business and just avoided Theodoseus like the plague. They completely ignored his very presence!
Thinking that a better location would give him the results he wanted, Theodoseus moved into the actual bathroom and sat next to the window across from the showerhead. The humans hardly reacted. They just closed him into the room and continued to use the other stall.
Hanging his head in shame, Theodoseus decided these humans were a new breed-- no longer afraid of his kind, and so he headed back into the jungle. He would wait each night, hoping to see these humans leave, and a new breed arrive. A new breed that he could once again torment and terrify.
