Changing a workplace

At last I have moved out on from this damn table! I worked for one a month sitting by with my back to the door (sorry, I really don't know how to explain it better). Anyone who moves beside passes by the door is looking at my monitor screen. That is not a crime, of course no! But English has a great word: privacy. Yes, that's the key. When you don't have privacy you feel uncomfortable. Even if you live in one room with 15 guys you need your own private space. Little but private, only yours. And other people may enter this space only if you would allow them to do so that. I tried to not to focuse on that. "Pfff... What's the problem with everyonebody seeing my screen? It doesn't matter because I am working!", I thought. But the little sense of little discomfort didn't leave me. No one cares about what I do and what is on my screen but I don't feel that I have privacy (privacy is a noun, you can't feel it) and it annoyed me.
But this morning I have moved away to... a nearby table. And now my back is lookin' at facing the wall. I am not sure if I feel comfortable, but I got an the idea to write a note for to you, my dear friend. Thank you and good luck.

Well done! 

What does it mean when you put three brackets together? ))) I see it a lot in Russian and in work written by Russian native speakers, but for the life of me, can't figure out what it signifies.
