doing homework

As a teacher I am kinda used to homework assignments, but generally to give a homework not to get homework... but this time it was different and well... exciting...

Nothing can ever happen twice.
In consequence, the sorry fact is
that we arrive here improvised
and leave without the chance to practice.

Even if there is no one dumber,
if you’re the planet’s biggest dunce,
you can’t repeat the class in summer:
this course is only offered once. - W. Szymborska, Nothing twice
