In 1967, a copy of the Iliad left the library of the Madrid institute of San Isidro on loan. The deadline was 15 days, but with Homer you always have to wait for a return, even if it takes years.

The person who returned the book could have ignored the matter after so many years. But he wrote a note of apology, looked for the recipient's postal address, went to the Post Office, waited for the book to be weighed and paid extra for it to arrive.
