My parents were dishonest people. If it was my birthday I knew my mother took me to the K-Mart and she stole my toy. She'd put it in the shopping cart and we'd walk out. I was raised with that.
In my early professional years I was asking the question: How can I treat or cure or change this person? Now I would phrase the question in this way: How can I provide a relationship which this person may use for his own personal growth?
