The etiquette of visiting differs, of course, in different parts of the world. In the city, where the dinner hour is late, as, for instance, in New York, visiting hours range from four to six, but people usually call between half-past four and five. In towns where dinner is served at any time between one and two o'clock visiting would begin at half-past three and cease at six, while where an earlier hour than this were the dinner one, visiting would begin at half-past two and end at half-past five. It has long ago ceased to be the vogue for even one's intimate friends to just "drop in." Wisdom, which comes with years, has taught people that no friend is so intimate that there may not be times when she is unwelcome, and even one's dearest and nearest bow to the law which suggests the paying of a visit at a time when one's friends are ready to receive.
