Men, women, and children need freedom to mingle on a human basis; and that means to mingle in their daily lives and occupations, not to go laboriously to see each other, with no common purpose. We all know the pleasant acquaintance and deep friendship that springs up when people are thrown together naturally, at school, at college, on shipboard, in the cars, in a camping trip, in business. The social need of one another rests at bottom on a common, functional development; and the common, functional service is its natural opportunity. The reason why friendship means more to men than to women, and why they associate so much more easily and freely, is that they are further developed in race-functions, and that they _work together_. In the natural association of common effort and common relaxation is the true opening for human companionship. Just to put a number of human beings in the same room, to relate their bodies as to cubic space, does not relate their souls. Our present methods of association, especially for women, are most unsatisfactory. They arise, and go to “call” on one another. They solemnly “return” these calls. They prepare much food, and invite many people to come and eat it; or some dance, music, or entertainment is made the temporary ground of union. But these people do not really meet one another. They pass whole lifetimes in going through the steps of these elaborate games, and never become acquainted. There is a constant thirst among us for fuller and truer social intercourse; but our social machinery provides no means for quenching it. Men have satisfied this desire in large measure; but between women, or between men and women, it is yet far from accomplishment. Men meet one another freely in their work, while women work alone. But the difference is sharpest in their play. “Girls don’t have any fun!” say boys, scornfully; and they don’t have very much. What they do have must come, like their bread and butter, on lines of sex. Some man must give them what amusement they have, as he must give them everything else. Men have filled the world with games and sports, from the noble contests of the Olympic plain to the brain and body training sports of to-day, good, bad, and indifferent. Through all the ages the men have played; and the women have looked on, when they were asked. Even the amusing occupation of seeing other people do things was denied them, unless they were invited by the real participants. The “queen of the ball-room” is but a wall-flower, unless she is asked to dance by the real king.
