Not only do I have a telephone in my office but it's connected to the outside world.
O frabjous day! Callooh! Callay!
The technician waved a wand over the line. (Literally—he had a machine that went ping.) Then he told me that the number had been diverted to another office. This was a bit odd as the previous incumbent had retired the year before, had not occupied the room for at least six months and hadn't been given another office. So who knows where the calls were going? Not me. And I don't care anyway. I have a working phone. Did I mention that already? A phone. That works.
