Many years ago, the office I worked at was across from some apartment buildings. I was working the night shift. One night, some of the guys told me they were going over to one of the other departments to watch this gal across the way. I went with them. We had to be careful because even though the lights were off, there were the one or two that are always on for who knows what. So we rolled some chairs over to the window and sat quietly for about 15 minutes. Our patience was rewarded when a nice looking young lady came into the apt. She went about her business while leaving the living room curtains open. The bedroom shades were closed, but from our vantage point, we could see as she moved from the bathroom to her bedroom. As it was late, she was already in the shut down mode and getting ready for bed. She was in her panties in the bathroom brushing her teeth. We could see her moving around. Before she went to bed, she came through the living room in her panties to the kitchen, passing right in front of the large picture window. Since the lights were off and the office we were in was dark, she probably didn't suspect there were 6-7 perverts watching her. With the light from the bedroom/bathroom, we were able to see her very well.
This went on for a couple weeks (not every night was something to see, several nights she was not even around). Then one night as she was walking out of the bedroom into the living room, she stopped suddenly and looked right across to where we were. Someone shouted for everyone to freeze. We do not know if she had seen a movement (maybe in the parking lot below since we were in the 2nd floor) or with the little bit of light did she spot us ? Put she went and turned her bathroom light off. That was the last time we saw her.
