I put up voiles on all my front windows at my old house after I got out of bed one morning and realised that there were a gang of builders congregating across the road who had obviously twigged I walk round naked in the mornings.
The house before (which was rented) had nets on the windows on the side that overlooked the road - I wondered why until I got up one morning to see a gang of Japanese tourists standing on the bridge opposite taking pictures. (It was a rather gorgeous house though).
