Ghostly Guest Bedroom: Supernatural Humor

The rattle was the warning. Lucrecia shrank back under her covers and pulled them up over her head, hoping that the dratted ghost would take the hint and vanish back into the attic. No such luck. The rattle grew steadily closer, accompanied by a ghastly moan. "Oh, for heaven's sake!" Lucrecia said, sitting bolt upright in the bed and throwing the covers back. "One night I could handle without a problem, two nights I could tolerate, but if you think that I'm going to let you ruin my sleep fro three nights running, you're just plain wrong!" under her breath, she added in a mutter, "I don't care if Aunt Mary is my favorite aunt, I'll send her up here to sleep in the spare bedroom instead of in my bedroom."

Inspiration: Cat bells rattling.
Story Potential: Medium-high. I'm not going to put it higher than that, but I do like the character and the set up.
Finished Length: Short story.
Notes: A haunted guest bedroom. An annoying ghost. An irritated woman. Told from a humorous standpoint. Honestly, I'm not sure what to classify this as. Usually, I'd say ghost=horror. But a humorous ghost story? Does that make it fantasy?
