Now thats SL for you. Find a sandbox, put your office there, do your work, take your office and go home! Look carefully, in the middle of the bubble is the designer at work. Like a cameleon, she uses the surroundings to make her clothes.
All thats missing is the ‘do not disturb’ sign… but an occasional shout does the job just as well and if really gets busy, just elevate the office to a few 100 meters.
