Back in college I had a job cleaning a bank at night. When I got there the first thing I had to do was take the elevator down to the basement to get my supplies. The elevator was still an old style manual elevator that required a person to be inside to operate the levers. It was interesting how the elevator operator was always very friendly to me. He knew my name and wished me well as I arrived to work each day. This was in stark contrast to the bank employees. Occasionally there would be someone in one of the offices working late. Without fail every single one of them pretended that I didn’t exist. Nobody ever so much as made eye contact with me. They would always be in some sort of trance, staring at the paperwork on their desk in silence.
