Dr. Arnold taught his brood the importance of diligence and dedication, even to the exclusion of a personal family life. Mother was more involved with the children but sought to teach them as the father would expect them to behave. This meant obedience, diligence, and honesty. It was a social structure that was accepted as the norm by those raised under its guidance, and the concept of gender equality would have to wait another generation or two. In large measure, this lifestyle molded Harley Arnold and his siblings during their youth.
