The obligation to attend an engagement, having once accepted an invitation, is so grave that should one die between the acceptance of the invitation and the event, one must ensure that one's executors fulfil such obligations.
I am afraid I have two alternatives, either to now retire to my library with a bottle of whiskey and a loaded revolver or to immediately catch the boat-train to the continent and head for Marseilles to join the Foreign Legion, though in the case of a priest I understand joining a very ascetic monastery in the remotest part of southern Europe or North Africa is almost acceptable, whilst "Society" holds my name in disdain as a cad and bounder.
Why? Because I forgot to go to this, having accepted an invitation:
Society of St. Catherine of Siena Annual Mass - 7 May 2009, Hospital of Ss. John & Elizabeth, St. John’s Wood, London The Society’s Annual Mass will be celebrated at 6.30pm by kind permission of Fra' Frederik Crichton Stuart, Grand Prior, in the Conventual Chapel of the Knights of Malta at the Hospital of Ss. John and Elizabeth in St. John's Wood. It will be celebrated as a Solemn Pontifical Mass in the traditional rite by Mgr. Malcolm McMahon OP, Bishop of Nottingham.
Mac has pictures which demonstrate my absence.
