A lot of people want to enjoy a trip to France, with the idea of having a nice vacation AND practicing their French. Unfortunately, they often come back saying: "As soon as I started to speak, the French would answer me in English".
If understanding French people speaking full speed is your goal, then by no means is listening to the French radio or watching movies in French the right path to get there. It’s as if you gave a first grader Shakespeare to read. It’s only going to lead to failure, loss of confidence and frustration.
