Under the rug
Long ago there was a man, he had grey hair that seemed to have been fading away. He lived in a rather old house. One day as he was reading his favourite novel, in his favourite chair, with his favourite pair of spectacles on, he saw something. He peered through the foggy spectacles at the rug. There it was again! He jumped away from the little mound that formed around his feet, and again when it started to scurry towards him. It made a strange strangled noise that sounded like a cow and a pig screaming at the top of their lungs, to the man. He looked around, desperate to find something to get rid of this small creature. He tried to crush it under his foot, it split in two. Mound reached mound and they congealed back into one thing. The man decided then and there what he was to do. He picked up a nearby chair and thrust it into the air. The small creature must have seen this, or heard it, or sensed it because it scampered under a table (with a lamp on it) and tipped it over. The lamp that had been on the table set the carpet on fire. Both the man and the small creature ran as fast as they could to escape the raging flames.
Only when the man was outside did he look down. There was the little creature, under the pavement. The man was bewildered, there wasn't any visible entrance to where the creature must have been. He couldn't see its body, only what must have been the pavement being pushed up by its body. The man, whose name was Gerald (his mother had been a sociopath) stared at his house. Flames left its windows and licked the sky. He felt something sniffing at his ankles and looked down to see the small creature. Rage filled him up like water fills a vessel, it poured out along his edges and tensed up his muscles. It had done this! So it had to die. The creature seemed to look up, it didn't. It bit down hard on poor old Gerald's leg. A scream escaped his lips as his skin started to change. It wriggled and morphed into what looked like the pavement, changing into the shape of a small mound. The small creature then died, for no apparent reason.
Many years later Gerald the mound found an old man. He played with the man, hoping this was the one who would set him free. He scurried along the boy's arm and bit down hard on his neck, finally ready to die.
