(The expression "calling acquaintance" is used to indicate the custom of ladies calling upon each other once or twice during the year as a social duty, rather than as a means of developing friendship.)
When calls are exchanged only once in twelve months it is an indication that only a purely formal acquaintance exists between two people. But when two women are friends, they may exchange calls at intervals of three weeks or a month, and sometimes very dear friends exchange calls every week. However, in this latter case the calls are more or less informal.
Calls of condolence, sympathy, inquiry and congratulation are usually answered by sending cards or brief notes to the caller. Later, on issuing from mourning, or on recovery of health, the calls of condolence and inquiry may be returned, but it is not entirely necessary, and depends largely upon the convenience and individual desire of the person on whom the call was made.
When a hostess is asked to invite the friends of her friends to a reception at her home, she is not obligated to return their "calls of duty." Nor does a woman return any of the calls, formal or informal, of her gentlemen acquaintances.
