For a number of reasons, the young female servants of the household slept in the bedroom of the lady of the house (which might be her own, or one she shared with her husband). Among the reasons for doing this was a desire to keep the girls out of trouble. Women were responsible for the management of the household, no matter what their station. While the wives of farmers and townsmen would also participate in their husbands' work (agricultural, manufacturing, or mercantile) their main function was "homemaking." For a noble lady, this was quite a chore. An aristocratic household would have anywhere from a dozen to over a hundred servants living with them. While the husband was in charge of the stable and security staff, most of the servants reported to his wife. The young female servants were the particular concern of the noble's wife. These were commoner servants, whose moral upbringing was the responsibility of their mistress. Women between the ages of 15 and 20 were considered sometimes "foolish and subject to the wiles of men." At the time, and until the better diets of the 20th century, many girls, particularly of the poorer classes, did not start menstruating until their late teens. Thus they had a few years to indulge their sexual curiosity without fear of pregnancy. The young men knew of this and sought to take advantage of it whenever they could . Getting pregnant before marriage was not considered a disaster for a commoner, and was sometimes encouraged before a match was quickly arranged. This approach provided proof that the union would not be a barren one. But rampant trysting was not wanted as it was unseemly, disruptive, and could get one in trouble with the Church.
