On not being a cat

Were I a cat, my love, I'd leave each day
a single dying mouse upon your bed;
Yet, human, I must find another way
And honour you by leaving verse instead.

I was challenged to summarise "Borrowable" in verse

One rainy day, Maria looks
To find her college Library Books.
Alas! her hopes were set to fall:
A Fiery Dragon stole them all,
And singed their keeper's beard, as well.
This incident may seem to spell
The ruin of this Ph.D.--
Or else, a switch to chemistry.
But such predictions turn out wrong:
She wasn't timid, all along.
Maria is the kind of maid
Who, even now, is not dismayed:
She cycles off to Oxenford,
For armour, courage, and a sword,
A recipe, a faithful friend,
And finds her thesis has an end.
