Esteemed Sir,
I tender to you my most sincere felicitations and confirm that I am in receipt of your correspondence of the 9th inst, with reference to that phrasing which should, or should not, immediately precede a person's signature upon the termination of their laying forth of information which is to be conveyed to another by the actions of servants of the Royal Mail.
With regard to the aforementioned, it is my most humble yet sincere opinion that any person or persons who do concern themselves greatly with such matters should have regard to a phrase which I am given to understand has become common parlance among many of the younger members of our society. I quote the said phrase here to you in its entirety. It is simply thus: "Get a life, mate!"
Assuring you of my most sincere and earnest attentions to your correspondence at all times,
I remain your most humble and obedient servant,
B. Chico (Esq)
