Two of my acquaintances are librarians, and both started work in a library on the same day.
They were summoned to the Head Librarian’s office.
After a short pep talk, he took out a bunch of keys and unlocked the stationary cupboard. “You’ll need some stuff”.
He took out a box of pencils, a box of pens, a box of notebooks, a box of rubbers, and a box of stanley knifes.
He gave them a pencil each, a pen each, a notebook each.
Then took the stanley knife, cut a rubber in half, and gave them a half each.
