We know that the Father is trying to teach his son something about patience and understanding...perhaps with how the son treats his own young child and Grandfather has noticed that there his son has a lack of patience. It also makes me think that the Father is teaching his son about patience because he has noticed that his son has a lack of patience with him. See how the son begins to understand what he may have been doing wrong and is remorseful? That's a good lesson in patience with the young and old. Thanks, Erika. I'm going to send this to my sister as she is our father's primary caretaker AND my sister is fluent in Greek.
