I drew diagram to help me explain the positions of objects in my room.
From top left to top right, the rectangle is the door, the next thing is my dresser, after that my cd shelves, then my desk and computer. going down from there, that oval is my office chair, the circle in the box is a small table where the lamp is, and the rectangle underneath that would be my bed. Oh and that small little rectangle thing between the lamp and the desk would be a window. The rest of the stuff you don't need to know about.
Now I like the lamp there because I'm usually on this end of the room, rather than the other end. Plus, everyone loves a lamp near their bed.
