That's it. The door, in the right hand foreground, is pushed up against the back wall. I'm in danger of going through the back wall whenever I push my chair backwards. The chairs on the left hand side of the photo are up against the opposite wall. I'm standing at the doorway, just outside the office, to take the shot.
In the centre foreground you can just make out an orange blob - that's my box. I don't have a filing cabinet, just a box on the floor.
As you can see, I'm not the world's tidiest person at work! That pile of files really needs to be straightened. Still, the pile is moved before I bring customers in (I put it on top of my very versatile box-on-the-floor).
Doncha love the paper party hat on the Happy Dragon in the background?
