In which I'm being haunted

So our ghosts are getting noisier--either that or I'm developing some sort of hallucinatory disorder because as I write this I'm alone in the house, television is off, no one is near the house, and I can hear faint conversations. (I already thought it might be the radiant heaters, but they're turned off...) I suppose it's fitting as we near Halloween that our resident haints--that's Southern for "ghosts"--might be getting up to mischief. A few weeks back I found an initial scratched into the kitchen chalkboard that I use for keeping grocery lists. We have jokingly called our female ghost Petrella because that is the name of the woman who owned the house in the 1950s and the only person ever to claim to see a ghost in our house described her as dressed in that style. And the letter I found etched into the chalkboard? A "P", of course. It does make you wonder...
