I think the only time you can be truly alone, is when you're in the bathroom; and then only when the door is locked, and windows covered. I have a window in my bathroom, and am very glad of the frosted glass and tree-branch shade. I think people forget sometimes that they are being watched. They don't think of the people in passing cars, or behind the windows in the buildings they walk by, Don't ever think that someone isn't going to see you, no matter how high or dense the fence, if you choose to prune your garden naked.
