Low Flying Lecturers.

A 9am lecture.
Student attendance is rather thin on the ground.
With his nose in a book the lecturer pretends not to notice and slyly gives latecomers another 5 minutes to appear.
Lecturer is so engrossed in his book he fails to realise his flies are undone.
You're flying rather low I want to point out.
But reminding myself of the student/lecturer boundary, decide against it.
9.10am, a latecomer wanders in and suggests to another student they go for a smoke.
They both leave.
The sound of the door closing behind them startles the lowflyinglecturer from his book, and the lecture (minus two nicotine casualties) begins.

The fly is now securely zipped.
