A morning call should not exceed from a quarter of an hour to twenty minutes in duration; the most proper time for such visits is between eleven and two o’clock; if your friends are people of fashion, from twelve to three will be the best hours.
LXVII.
If the persons called on be not at home, leave a card for each person to whom the visit was designed, or beg the servant to mention that you inquired for so many persons.
LXVIII.
The subjects for conversation should harmonize with the character of your visit, and prevent your introducing a gay conversation, when paying a visit of condolence; or subjects requiring deep thought, upon casual visits or calls of ceremony.
LXIX.
In making friendly calls almost all ceremony should be dispensed with. They are made at all hours, without much preparation or dressing.
LXX.
Visits of ceremony should be paid after a nearly similar interval has elapsed from when they were made. People in this way give you notice whether they wish to see you seldom or often.
