The door to the coat closet and the new thermostat

The door to the hall or coat closet opens by itself at random intervals. Before I had the new digital thermostat install, it was a complete mystery. However, the new thermostat has helped solve the enigma.

The closet door opens when the temperature changes. I know this because the new thermostat is sensitive enough to record one-degree changes in temperature. Every time I see the door open, I check the thermostat before I close the door. I also check the thermostat when I to the bathroom or one of the bedrooms. This way, I am aware of the temperature inside the house at all times.

I suspect the door only opens when the temperature goes down, but I am going to wait a couple of months before I make a definite decision on that. That closet is below the entrance to the attic, which no longer has an entrance cover. I think that may be the reason the door opens by itself. I am going to have to get a cover for the entrance to the attic.

In the mean time, I am going to use the door opening by itself in a short story. I think I will use it in a ghost story, I have not written in this genre; therefore, I am going to let the door inspire a ghost story.
