There are a few apartment and townhome complexes along the Sammamish River Trail. Some people don't realize or don't care that during the wee hours of the morning when it is dark outside and your apartment lights are on, people along the path can see inside if you don't keep the shades drawn.

There are a LOT of people who wake up and go about their normal morning without clothes. Cooking breakfast, watching the morning news, making coffee. I've seen a naked couple doing their morning workout routine to some fitness video. My all time favourite, though, was the woman in her underpants (bottoms only) and slippers, sitting on the stairs off her porch, drinking a cup of coffee and smoking a cigarette, waving and saying "good morning" to all the cyclists riding past.
I rode past, then sprinted up to catch the person 50 yards or so ahead, just to ask "Did we really just see that?"
