If you’re a doctor, you want to sound like a doctor when you’re diagnosing a patient. If you’re a plumber, you’d better speak like a plumber when you’re explaining an estimate. If you’re a hairdresser, a fireman, a lawyer, a zookeeper, a principal, or a porn star, you want to sound as if you work in your line of work when you are, in fact, working. But nobody wants to sound like a politician, especially a politician.
