The teacher does not so much tell the story as ask the story. The teacher will usually use a skeleton script with very few details, and then flesh the story out using details provided by the students in the target language, making a personalized story for each class. Using the circling technique, teachers can ask for these new details while still keeping the target language completely comprehensible. Advanced TPRS teachers are able to improvise, creating stories solely based on student answers to questions about the day's vocabulary structures. The focus is always on the target structures, allowing the details to support those structures.
