The Girls' Friendly Association of the Protestant Episcopal Church is a notable exception to this rule.
In a large New England city, not long ago, a member of the Woman's Club proposed to establish a club especially for domestics, since no other class of women seemed willing to associate with them.

The proposal was voted down.

"For," said the women, "if they had a clubroom they would be sure to invite men, and immorality might result." But there is no direct connection between a clubroom and immorality, whereas the park bench after dark and the dance hall and its almost invariable accompaniment of strong drink are positive dangers.
The housekeeper simply does not realize that her domestics are _girls_, exactly like other girls.

They need social intercourse, they need laughter and dancing and healthy pleasure just as other girls need them, as much as the young ladies of the household need them.
Perhaps they need them even more.

The girl upstairs has mental resources which the girl downstairs lacks.
