It's the best place I've found in the building to work after my afternoon teaching duties. It's a bit makeshift but it gives me space: physically and mentally. And a place like that is important to most of us. Our environment affects our mind, which in turn affects our ability to work. And if you can keep your hidey hole fairly secret, you'll not be disturbed that often either!
Have you found your hidey hole yet? Your little oasis of calm within the walls of the school? I'd really recommend finding it and using it on those occasions when the office or your classroom just isn't doing it for you.
A place with a window is ideal - a reminder that out there is a world which doesn't depend on what you're doing, a world which won't come crashing down if you don't get your work done. A window gives perspective. Reminds you that school isn't the be all and end all.
The cats who cross the road, back and forth, back and forth, will go on doing so. The city will continue in its frenetic activity, never really sleeping. Your world can be a bigger place than your job; a room with a view will help you to remember that.
