So whats the problem? Are you upset they arent turned towards you?
Seriously if you don't want people to see you then completely encase your space. But worrying about what others are doing is pretty trite.
@Stealth83: I interpreted this as my neighbors peeping through the fence looking at me in my private space. Not that I would be doing anything outside that would be naughty (well, maybe at night in my own pool sans a swimsuit) but again, that's a different story entirely. 4951
