OK, I am taking myself far too seriously lately, so let’s have a little fun. Learning a language, we get lots of input. But for EFL students, it is usually a very standardized kind of input. Students think they need the perfect British or American speaker to be there model. Learning “World English” means you need to expose yourself to lots of different accents. Even within a country there are many different accents.
But what about when someone is drunk, or on drugs. They tend to speak differently too. It is a skill to be able to understand them. Here is a kid, just after the dentist, talking to his father in the car. I find it hilarious. The kid looks a lot like my little brother at that age.
