This, by all standards of teaching, should be a lousy series of lessons.
HOWEVER - we were required to deliver the lesson as announced in the
quarterly ("unified curriculum" - also called unfried
curriculum). But we didn't have to use the rather trite set of comments
which passed for a lesson. So we didn't.
There are some unusual studies in here. Since you're here, and you have
some time on your hands, browse around. You never know what you find in
the attic of the mind.
