While you're at it, install wind chimes. They drive at least half the population bonkers. The other half may wave and say how pretty and relaxing they are... and you'll find out maybe not all the world is detestable.🙂Or, you could move to a rural area like I did. The windows are open and the sparrows are singing. 😉

Having a private balcony also can also say ' Because I am a considerate neighbour, I am arranging the space so that you do not have to look at me and all my stuff all the time.'

Beauty is in the eye of the beholder, but sometimes it's better that the eye be nearsighted.

Ah, circumstances forced you to move and you're unhappy? There's a huge difference between waking to robins singing and garbage trucks rumblings. Perhaps softly listening to your favorite could soften the sounds and soothe your heart?
