Unless you have some good reason for not doing so, let your friends know the day, and, if possible, the hour when you expect to arrive. Surprises are very well in their way, but there are few households in which it is quite convenient to have a friend drop in without warning for a protracted visit. If they know that you are coming, they will have the pleasure of preparing for you and looking forward to your arrival, and you will not feel that you are disturbing any previous arrangements which they have made for the day. Let your friends know, if possible, soon after you arrive, about how long you mean to stay with them, as they might not like to ask the question, and would still find it convenient to know whether your visit is to have a duration of three days or three weeks. Take with you some work that you have already begun, or some book that you are reading, that you may be agreeably employed when your hostess is engaged with her own affairs, and not be sitting about idle, as if waiting to be entertained, when her time is necessarily taken up with something else. Make her feel that, for a small part at least of every day, no one needs to have any responsibility about amusing you. A lady who is charming as a guest and as a hostess once said to me: "I never take a nap in the afternoon when I am at home, but I do when I am visiting, because I know what a relief it has sometimes been to me to have company lie down for a little while, after dinner." Try, without being too familiar, to make yourself so much like one of the family that no one shall feel you to be in the way; and, at the same time, be observant of those small courtesies and kindnesses which all together make up what the world agrees to call good manners. Regulate your hours of rising and retiring by the customs of the house. Do not keep your friends sitting up until later than usual, and do not be roaming about the house an hour or two before breakfast. If you choose to rise at an early hour, remain in your own room until near breakfast-time, unless you are very sure that your presence in the parlor will not be unwelcome. Write in large letters, in a prominent place in your mind, "BE PUNCTUAL." A visitor has no excuse for keeping a whole family waiting, and it is unpardonable negligence not to be prompt at the table. Here is a place to test good manners, and any manifestation of ill-breeding here will be noticed and remembered. Do not be too ready to express your likes and dislikes for the various dishes before you. The wife of a certain United States Senator once visiting acquaintances at some distance from her native wilds, made a lasting impression upon the family by remarking at the breakfast-table that "she should starve before she would eat mush," and that she "never heard of cooking mutton before she came East."
