When you direct a letter to a knight bachelor--though it is indeed customary and well-bred to omit altogether the Knt.--yet it will never be taken amiss should you venture to address him as a Knight of the Garter, Bath, &c. &c., or even as a Baronet. Undoubtedly it is as vulgar to misapprehend and confound titles, as it is to mispronounce and misspell names; nevertheless rest assured, that flattered vanity will go far to pardon vulgarity. If a gentleman, pay infinite attention to the single ladies of a family--compliment, flirt, converse with, and ask them to dance. This conduct will obtain for you, on account of the fair creatures, marvellous good report, numerous invitations; and if you have sufficient tact to steer clear of committing yourself for more than a few flattering and general attentions, you may be considered one of the happiest of those who live--by their wits, and upon their friends. Should your "dancing days be over," which is scarcely probable, considering how greatly it is now the fashion for "potent, grave, and reverend signors," and signoras also, to join the gay quadrille, &c. (and here we may as well note, that in genteel society, dowager honourables and old ladies may dance, whilst young, plain misses may not)--there are sundry modes of rendering yourself agreeable, which your own taste and talents, it is to be presumed, will naturally suggest: chess, whist, ecarté, quadrille, &c. &c., not to mention a little practical knowledge of music, are acquirements which cause an individual to be considered "very agreeable"--because very useful; and rely upon it, as the world goes, utility in nine cases out of ten is, with society, a consideration. Hence, no creature is so universally voted disagreeable as one from whom no kind of service can be exacted; and whilst roués, gamesters, and tipplers, duelists, pugilists, and blacklegs, are tolerated in society, stupid men are overlooked, or thrust out of it with contempt. Dress in the extreme of fashion: you can neither gain nor maintain your ground without so doing; and as you have an end to answer, which your tailors or milliners have not, of course you will not suffer the unfashionable dictates of conscience, respecting their bills, to interfere with your proceedings. Answer an invitation as soon as it is received; many individuals defer so doing for some days, which certainly shows fashionable ease and nonchalance, besides allowing time for the arrival of another and preferable one; but, by those who are absolutely bent upon advancing themselves in society, this practice is to be eschewed, since by perplexing, it so annoys the donor of a fête, that the chances are greatly against your ever again being asked.
