Clock-watching

MrsM has been signed up for a Time Management course.
MrsM is aggrieved. She does not think that she needs to attend.
MrsM is informed that it is compulsory.
MrsM provides a credible excuse for the first session:

"Board Meeting"

MrsM provides a credible excuse for the second session:

"Recruitment"

MrsM runs out of excuses.

MrsM checks her diary first thing in the morning. It is The Day.
MrsM shakes her head at the shocking waste of time.
MrsM arrives with a minute to spare.

There is no-one there.
MrsM is a week early.
MrsM turns around to see the course organiser.
MrsM is busted.

Alas! MrsM knows that the course organiser knows that
MrsM really, really needs a Time Management course.
And the course organiser knows that MrsM knows that.

It is a bitter medicine to swallow.
