That specific creeping behavior is hilarious. Several years ago, my daughter and I found a lost dog clearly a family pet near our home near a busy road. We trapped it in our shaded yard and went around with some quick flyers to find the owner as we knew it was one of 30 homes. Multiple people revealing as little of their eyes as possible through blinds and curtains became funnier and funnier.
(Eventually we found the home. The mother said their dog was in their basement, and we almost left without a flyer until her daughter ran to the door and said their dog was missing and identified her and then the mom was willing to come get the dog. Strange episode.)
