An elder and his wife were in my apartment building this morning. I live on the 3rd (top floor) and I heard someone walking up the stairway very slowly and silently. They arrived at my door and didn't knock and didn't ring. I knew someone was just outside the door. They either were at my door, or the door right next to mine(3 feet away) Usually I hear a person ring or knock, even if it's at the neighbors door, right next to mine. So I went out the back door, down the staircase and up the front staircase where they were, and I saw them at the neighbors door, 3 feet away from mine. They didn't knock nor ring at her place, because I asked her afterwards. Every door in that apartment building has a Christmas decoration on it, except mine. Last year they came a few days before Christmas day also. I guess that they wanted to spy on me somehow. When they saw me in the front staircase, they turned around and looked at me ill at ease so they said hello. They must have felt stupid standing there right next to my door and not knocking, just listening as if they were knocking at the neighbours door. I said a fast hello, just to be polite and turned around quickly when I saw that it was them and went back up the back staircase. They quietly left the building without knocking at any other door.
They come only once a year in my apartment building, and always a few days before Christmas thinking they might find some kind of Christmas decoration at my door. I never decorate, I just play lotto, you stupid elders.
