Haunted house

Ted and I think we might be living in a haunted house.  The plastic mat inside the front door has been moved twice recently and neither of us moved it.  The first time was a surprise, but having it happen twice is just weird.

This is how we noticed the plastic mat today–nicely centered in front of the door.

This is where we’ve had the mat for nearly 20 years–to the left of the door.  The teeth on the underside of the mat keep it from sliding across the carpet, so it stays nicely in place.

When we moved the mat from the center to the left, “holes” from its center placement were evident in the carpet.  None showed from moving the mat to the center.

The mat looks nice from indoors when it’s centered on the door, but it’s more useful to the left of the door when people enter the house.

 

Questions:  How/who moved our door mat twice?  Is our house haunted?  If so, do we have an anal-retentive ghost who is fixated on centered doormats?  Inquiring minds want to know.
