Sorry, until you look closely at what is said and done with the materials,
activities and discussion in class you don't know what I may or may not
have "imposed" on the students.  Your assertion concerning what I have done
is made without adequate knowledge of the details of the actual practice.
I can only imagine you have made assumptions about what I have done based
on your practice.
