Or greet everybody throughout the day in your target language even if they don't understand what you're saying. The idea is that by doing this learners subconsciously become accustomed to the natural rhythms and melody of that language. Similarly, try reading magazines and newspapers in the target language even if they're beyond your level. Don't miss out on possible learning opportunities. If you've rented a video, for example, look carefully at the credits before the film starts.
Gestures are also rich sources of cultural and paralinguistic information.
Think about other ways you could use this technique. Try getting a hold of a box of cereal, for example, a menu, or a skiing brochure. Don't overlook the possibilities of the Internet for language learning. You don't always need to listen to what is being said. To help your pronunciation and fluency, try listening only to how something is said for a while.
