MasterM is writing a letter to his new Commanding Officer. With a fountain pen.
I have the honour to inform you that following my commissioning...I will be reporting for duty...at 0700 on Monday x January.
Various pleasantries follow until the letter concludes
I have the honour to be,
your obedient servant,
Letters like this have been written by successive generations of young officers. It may seem an anachronistic tradition in an age of email and text message but the structure of the letter is designed to introduce MasterM, giving information about his achievements and interests. In return MasterM will receive a hand written letter of acknowledgement and welcome. These formalities ensure that working relationships and new teams can be established as quickly as possible.
MrsM ponders the vision of MasterM as an obedient servant and concludes that miracles must happen after all.
