X.
If, in travelling, any one introduces himself to you in a proper and respectful manner, conduct yourself toward him with reserve and dignity, yet with ease and politeness; and thank him for any attentions he may render you. If he is a gentleman he will appreciate your behavior; if he is not, he will be deterred from annoying you. All such acquaintances cease with the occasion. Converse only upon topics of general interest; it is necessary only to be civil. If he should betray the least want of respect, turn from him in dignified silence; a lady by her behavior always has it in her power to silence the boldest.
XI.
If on paying a morning visit you meet strangers at the house of your friend and are introduced, it is a mere matter of form, and does not entitle you to future recognition by such persons.
XII.
Be very cautious of giving a gentleman a letter of introduction to a lady,—it may be the means of settling the weal or woe of the persons for life.
XIII.
If you have an introductory letter, do not deliver it yourself, unless upon cases of urgent business, but send it with your card and the number of your lodging, enclosed in an envelope, as soon as you have made yourself comfortable after arriving at your destination.
