For the past couple of days I have had the unmistakably bizarre experience of riding in a rather full elevator with one or more people conducting a conversation, in a natural tone of voice, on their mobile phones. Perhaps this is not unusual. It just happens to be outside of my realm of personal experience. I think I would be hyper-conscious of stepping into an enclosed box in the close proximity of a few other individuals while conducting a personal conversation. But maybe that’s just me. Odd? Or not odd?
