An ultra-short piece of FlashFic, or Halloween:
Billy asked his father, on one occasion, if the house opposite theirs was haunted. He never saw anyone go in or out. Only saw lights go on and off, at various times, during the day and night. And shadows – there were always shadows in the windows.
“Yes,” his father had answered him, “But not by ghosts.”
Upon pushing him to elaborate, he explained that the house belonged to an old eccentric who was very much alive, “In the technical sense.”
“You see, boy,” he said. “You don’t have to be dead to haunt a place.”
