Dentist chair

"Hello hello, this is your dentist calling." It was 7.45 on a grey London morning, and there he was on the phone. "It is time for your check-up." Was this real? Was I awake, or dreaming it? Was he outside the front door? Only the fact that my dentist is a British Asian with an Indian lilt stopped it from being the opening scene of some sort of slasher movie.
