Theodore Roosevelt said this quote

To all who have known really happy family lives, that is, to all who have known or who have witnessed the greatest happiness which there can be on this earth, it is hardly necessary to say that the highest idea of the family is attainable only where the father and mother stand to each other as lovers and friends. In these homes the children are bound to father and mother by ties of love, respect, and obedience, which are simply strengthened by the fact that they are treated as reasonable beings with rights of their own, and that the rule of the household is changed to suit the changing years, as childhood passes into manhood and womanhood.
