Final answer:
Frank's behavior towards his friend Pat showcases the early developmental understanding of friendship in children, reflecting the learning of cooperation, mutual trust, and the development of theory of mind. Parents can help guide children through this phase, implicitly teaching them about the value of deeper, more enduring friendships.
Step-by-step explanation:
When Frank, a kindergartener, flip-flops on his friendship with Pat based on daily disagreements, it's indicative of the developmental stage of young children where the understanding of friendships is still evolving. During the ages of six to ten, children are developing their theory of mind (TOM), which enables them to recognize that others have different thoughts and feelings. Aristotle's distinctions between incidental friendships, which are based on utility or pleasure, and perfect friendships, which involve a deeper level of mutual goodwill and virtuous development, can help us understand Frank's behavior. Frank's parents might find it beneficial to observe this behavior as a part of his social development, rather than a cause for concern, and guide him towards learning about mutual trust and cooperation, helping him build towards more mature friendships as he grows.
