Do not visit upon a child the misdemeanor of his elders. If you have
reason to believe that a child’s parents talk against you, visit them
with a determination to show them that you have their child’s best
welfare at heart. Show them that you understand him by pointing out
wherein he excels, and where you hope to strengthen him. Be sure that
they see your attitude of genuine friendliness.
Never attempt by force to make a child show friendliness to you.
