When I entered the living-room, about an hour ago (16:10), it was already quite dark. My attention was drawn by a mysterious light on the wall. Couldn’t be the sun, I thought, and stepped into the light. I turned my head in it’s direction to see where it was coming from. It appeared to be the sun after all, but indirect. The sunlight reflected in a window of one of the houses in the block around the corner, about a 100 meters away, and was projected straight on my wall. Pretty good aiming!
