Today I am participating in a long conference call and so I camp out in a vacant office so I can close the door and put the phone on speaker. The office overlooks Adelaide Street and one of my favourite downtown buildings, the Canada Permanent Trust building. I get watching the office workers on several floors and it strikes me that each floor is a separate world of its own, each person oblivious to the others moving about above and below. That gets me to thinking about the thousands and thousands of office workers moving about the the windows of all the office buildings downtown, like worker ants. The thought of being a worker ant makes me a little depressed so I turn my attention back to the meeting and get on with my job.
