This happened to me about twenty years ago so I may have some of the details wrong. This is what happened to the best of my recollection. It takes a little set-up so bear with me and I will be vague about certain things to protect not just my identity but the identity of the other person involved.
I was still in my Active Duty Army days and stationed at a base somewhere in the South. At this particular point of time I wasn’t living in the barracks like most single enlisted soldiers. A fellow sergeant I had worked with (let’s call her T, which is not her initial) had just kicked out her husband and was looking for a housemate to help her meet expenses. Her dog Monty (not his real name) gave me the seal of indifference (the dog didn’t like anyone so that was as good as it got) so I moved in. It was pretty much a platonic sitcom situation (Man, Woman, and Dog - coming soon to Fox).
T had mentioned seeing a figure in a uniform in the house before. (It was the South and there was a Civil War battlefield nearby.) She was a grounded person so I believe she believed she saw something.
One afternoon I was at home while T was working so it was just me and Monty. I was preparing dinner and had set aside the cover from the burner I was using. (T had a set of burner covers similar to the ones shown.) I noticed the burner cover wasn’t where I had put it. I searched the entire kitchen going through all the cabinets and any other spaces it could be even though I knew where the cover should have been.
Frustrated from the fruitless search I grabbed a beer from the fridge and went into the living room. I asked Monty where the cover was but he didn’t answer. I returned to the kitchen and all the covers were off the burners and stacked next to the stove. It was time for another beer.
I don’t know if T believed me when I told her what happened but at least she didn’t laugh in my face. I think Monty knew more than he let on though.
