In our basement, we have old-style ceiling tiles stapled to the ceiling. The ones soft enough you can punch through. The computers and my videogames and tv are all in the basement. While I'm typing this, I can hear scampering back and forth in the ceiling. I had a suspicion a couple of days ago, but wasn't really convinced until I heard squeaking noises overhead. It doesn't seem to bother me that much because it's just running around on top of the ceiling tiles. Personally I loathe centipedes more than mouses. In fact, I'd like to meet Mr. Jingles one day. I only pray our first meeting isn't by him jumping down my shirt.
