“Many parents are more interested in what is going on in their own social circle than in what is happening to their children. Others spend their evenings in the local bars instead of staying at home and fulfilling their family responsibilities. Some say, "I am working to provide for my children, and I don‘t have time for play." When both parents are working away from home, children, left to themselves, naturally get in trouble. Boys and girls who find neither comradeship nor entertainment at home naturally seek it at the corner drugstore or in less desirable places, where they have too much freedom and too little discipline. Many communities are making studies of the causes of juvenile delinquency. The results show that the first cause is lack of parental care.“
