Its sounds so odd to miss people you dont even know. A 40 person project group in my workhall is shifting to a building next door. The thing is, I have never worked with them and never found the need to interact with any one of them on a personal level either.
But I had got so used to them moving about, always keeping the workhall sort of alive. On the odd weekends or late nights that I had to work, I knew some of them would always be there and I never felt lonely.

Its their comforting presence that I shall miss, very badly.
