"Wavy handed" people on TV. Some seem unable to speak without waving their hands about. If you mute the sound, you'd think they were doing sign language.
When I was at a UK grammar school in the late fifties. We used to have double English every week. At some point in the lesson there was always an exercise on "Public Speaking."
A different member of the class had to stand in front of the rest of us and give a two-minute talk on any subject they chose.
You were expected to conduct this with your hands behind your back.
Any hesitations, the inclusion of any "ums" or "ers." and you'd likely find a soft blackboard rubber aimed at your head, thrown by the master sitting at the back of the class. Plus howls of derision from the rest of the class. Through sheer pressure, we all became quite good at it. I found the ability very useful in meetings during my career.
Yet I find there are some people on TV, particularly older men, "who must have gone to the same school."
TV adverts that have disclaimers at the bottom of the screen that are hard to read. So many of them.
What you see on the screen should be exactly what they are selling. Car adverts where it says, "model not available in your country." Phone adverts where it says "sequences shortened."
I could go on....
