This book is about the unfair judgment, which sometimes the children undergo to their parents, completely ignoring all the sacrifice involved in protecting, maintaining, educating children.
If the children can discern the value of their parents, they would be grateful children, despite of the circumstances that they endure in the relationship with their parents, either the absence or lack of moral support or financial support.
Life is a school, and sometimes its lessons are hard. It is important to learn the lessons on time, not when it is too late, to prevent or repair errors.
In the Holy Scriptures, there is a Divine commandment: Honour thy father and thy mother: thatthydays may be long upon the land which the LORDthyGod giveth thee.
