We have an inexplicable number of houseflies at Moogie's Manor. There are no open windows; doors aren't open for long. The only possible fly source we can postulate is the Labrador size doggie door.
The doggie door is in the laundry room, which is near the Master bedroom and bath. Most of the flies seem to wind up in our bathroom where we're often easily able to smash them with our bare hands.
(I know -- gross, right!?!?!)
So. This odd separation of flies and inhabitants leads me to a new conspiracy theory.
The houseflies are NSA drones. Checking up on the goings on at Moogie's Manor. Right?
Sometimes they are really out to get you.
