Twice this morning, I have left my room and come back only to discover the light has been turned off. I either have a poltergeist or am losing my short term memory. Either is a distinct possibility.

Another weird thing: I was sitting here working and I heard a bird chirping. It didn't sound like it was coming from outside but inside around the kitchen. I heard it twice. So did Elliott. He sprang up from his deep catnap and bolted into the kitchen looking for his potential prey.

Yep. Definitely a bird-chirping, energy-efficient poltergeist.
