There was a substitute who gave us a really hard test that our regular teacher had never mentioned. She didn't explain anything and just expected us to know all the answers. It was so mean of her. She also graded it harshly and many of us got bad grades for no good reason.
Well,'stretched by teacher stories' might imply that the stories told by teachers have been elongated or over - elaborated. For instance, a teacher might stretch a historical event story to include more details that are not entirely factual but are used for educational purposes like making the story more engaging for students. Sometimes teachers do this unconsciously to make the learning more interesting.
A mean teacher might be one who publicly shamed students for getting answers wrong. For instance, in an English class, when a student mispronounced a word, the teacher would make them repeat it several times in front of the whole class. This was embarrassing for the student at the time, but in the long run, it made the student more determined to improve their language skills and they became very good at public speaking later.
One mean teacher name could be 'Mr. Grump'. It gives the impression of a grouchy and unkind teacher. Another option is 'Miss Scowl', which implies that she is always frowning and not very pleasant. 'Professor Stern' also works as it shows a strict and perhaps mean - spirited teacher.
It could mean that a teacher is using improper means to coerce or blackmail someone regarding fantasy stories. Maybe the teacher is threatening to expose something related to the creation or sharing of fantasy stories in an unethical way.
It could mean that the teacher attaches or links to the students' stories. For example, the teacher might use the students' personal stories as examples in teaching certain concepts or values. Maybe in a writing class, the teacher pegs a student's story about a memorable trip to teach descriptive writing.
They can be very motivating. When students face a mean teacher, they often strive to prove the teacher wrong or to meet their high expectations. So it can lead to better academic performance.
It could mean that your teacher enjoys the stories you write or tell. Maybe you are very creative in your storytelling, and your teacher appreciates that.
