The fact that people below a certain age seem to be unable to converse in a way that does not make me want to brain them with a blunt object. I watched a video phone review and after 4 minutes or so the awful diction, bizarre inflections, random uses of 'like', 'sort of' 'I'm going to go ahead and say" and similar nonsense filler just made me turn it off.
Why do people think it is somehow useful to come across as a bit dim?
