Privacy is important, especially when you live in a big city. There is so much going on in the world that when you come home you just need a place to relax. You don’t want anybody bothering you or anyone in your space when you get home. You want to be able to shut your doors and forget about everything and everyone else. It’s essential for decompressing. This includes your outdoor space. 

To have outdoor space in a big city is a rare treat, so you probably relish it if you have it. You love sitting out with a book or a cold beverage, feeling somewhat at one with nature, even in the small way that you can. You love being out there by yourself or with a friend, and you value that space more than most. So it follows that you want to keep it to yourself.
