Torrents

A problem frequently occurs as you become more fluent in your chosen language. As you manage things quite well, the native speakers all begin to think you are quite fluent and good at their languages and they answer you in a torrent.
Number one rule: do not panic. Anticipate what they might say and work out your reply. Take your clues form others around you – in the shop or café, for instance.
If you really do not understand, insist and insist until they speak slowly enough and / or simply enough so that you can understand.
One day, this will stop happening and you will get the upper hand.
Until that day comes, practise as much as you cane.
Team up with someone form your class and practise dialogues met in class. Try saying them with different moods and emotions for variety. And keep on anticipating those turns and torrents.
