17.  Secrecy is another characteristic of good-breeding.  Be careful not to tell in one company, what you see or hear in another; much less to divert the present company at the expense of the last.  Things apparently indifferent may, when often repeated and told abroad, have much more serious consequences than imagined.  In conversation there is generally a tacit reliance, that what is said will not be repeated; and a man, though not enjoined to secrecy, will be excluded company, if found to be a tattler; besides, he will draw himself into a thousand scrapes, and every one will be afraid to speak before him.

18.  Pulling out your watch in company unasked, either at home or abroad, is a mark of ill-breeding; if at home, it appears as if you were tired of your company, and wished them to be gone; if abroad, as if the hours drag heavily, and you wished to be gone yourself.  If you want to know the time, withdraw; besides, as the taking what is called a French leave was introduced, that on one person’s leaving the company the rest might not be disturbed, looking at your watch does what that piece of politeness was designed to prevent:  it is a kind of dictating to all present, and telling them it is time, or almost time, to break up.

19.  Among other things, let me caution you against ever being in a hurry; a man of sense may be in haste, but he is never in a hurry; convinced, that hurry is the surest way to make him do what he undertakes ill.  To be in a hurry, is a proof that the business we embark in is too great for us; of course, it is the mark of little minds, that are puzzled and perplexed when they should be cool and deliberate; they wish to do every thing at once, and are thus able to do nothing.  Be steady, then, in all your engagements; look round you before you begin; and remember, that you had better do half of them well, and leave the rest undone, than to do the whole indifferently.

20.  From a kind of false modesty, most young men are apt to consider familiarity as unbecoming.  Forwardness I allow is so; but there is a decent familiarity that is necessary in the course of life.  Mere formal visits, upon formal invitations, are not the thing; they create no connection, nor will they prove of service to you; it is the careless and easy ingress and egress, at all hours, that secures an acquaintance to our interest, and this is acquired by a respectful familiarity entered into, without forfeiting your consequence.

21.  In acquiring new acquaintance, be careful not to neglect your old, for a slight of this kind is seldom forgiven.  If you cannot be with your former acquaintance so often as you used to be, while you had no others, take care not to give them cause to think you neglect them; call upon them frequently though you cannot stay long with them; tell them you are sorry to leave them so soon, and nothing should take you away but certain engagements which good manners obliged you to attend to; for it will be your interest to make all the friends you can, and as few enemies as possible.
