How to deal with neighjbors...

...who can possibly look over the fence? I've seen a lot of topics but the most recent one close is about "...how close are your neighbors..." almost a year ago. Sometimes I see neighbors' heads but if they are closer to the fence they do not need any help to get the full picture. I am building my pool and plan even more time outside in the nude. My friends will learn that pool and spa area is clothing optional...not to say nude for me. My 21-yo son is OK, my GF is naked with me too. How do you deal with neighbors, do you care? Did you tell them what to expect when they sneak over?
