For readers with no Italian, an official English translation has been issued:
To all School and House Prefects
The Headmaster has asked me to write to you all on the subject of Absits.
It has come to the Headmaster’s attention that boys have been seen in the town at coffee shops, tobacconists and – in some instances – bars. This may lead to association with undesirable elements.
Prefects are reminded that they are in positions of trust, and that the rules regarding Absits apply to them as well as to other boys.
The Headmaster needs to know the whereabouts of all Prefects at all times. They may only leave the perimeter of the school with a duly authorised permit, and for legitimate reasons.
Angelo Card. Sodano
