I have a neighbor who lives in a second story condo. His balcony overlooks my backyard. It is mostly hidden from his view by trees, but there are a few gaps where nothing obstructs the view. A couple years ago on July 4th, I was in my backyard naked, not paying any attention to who might see me since my yard is 90% private. I heard voices and looked to see this neighbor had company, and they were all on his balcony and had seen my naked self. I just kept on but tried to stay out of their view. Next thing I knew, my neighbor had come over to ask me to borrow my ladder as they were going to watch the fireworks from his roof. At this point, since all had seen me already, I just went to get said ladder in view of the others on his balcony, was introduced to them - so yeah - this neighbor has seen me quite a bit.
