Silent Erosion

There is one more thing in my house that should not exist. At first, it was an old chair with a sudden color, placed quietly in the corner of the living room. My wife and I both thought the other party bought it, and neither of us cared. Then, a plate with an unfamiliar pattern appeared in the kitchen cupboard, and a pair of slippers that I had never seen before appeared under the bed in the bedroom. They appear without any reason, but they are "reasonably" integrated into our lives, as if they have always been there. We begin to forget. Forget when these things appeared, and even slowly forget that they "originally didn't exist". Until that day, deep in the drawer of my study, I found a leather-bound photo album that I had never purchased. I opened it with trembling, and it was filled with photos of "us" - from childhood, to marriage, to many moments that never happened. "We" in the photo are smiling extremely happily. The last page is blank. There is a line of small handwriting written on the side, the ink is very fresh: "Tomorrow, there will be new photos posted here. It's a family photo of the three of us." However, my wife and I have no children at all. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
