(1) In the late nineteenth century, proper heterosexual courtship took the form of "calling." (2) When a young woman reached marriageable age, she was allowed to receive male callers in her home, under the watchful eye of a chaperone. (3) The entire calling system was controlled by women and took place in their sphere. (4) A young man was allowed to pay a call only if he was definitely invited by a young woman or her mother. (5) It was considered highly unsuitable for a man to force his attention on a lady by making the first move. (6) By the mid-1920s, an entirely new system of courtship—the date—had taken over. (7) Couples who dated no longer sat together in the front parlor of a private home. (8) They went out to theaters, restaurants, and dance halls. (9) This move into the public sphere gave couples unheard-of freedom. (10) It also changed power relations between the sexes. (11) Men, who controlled the public sphere, now controlled courtship. (12) Now women were forbidden to take the first step. (13) According to mid-twentieth-century advice manuals, girls who refused to respect "the time-honored custom of waiting for boys to take the first step" would ruin a good dating career.
