What is the role of a nephew in an uncle or aunts life. There is nothing in particular that is uniquely nephew-like behavior. His relationship with his uncle or aunt is his and their choice. There are no expectations for the relationship. The thing that they have going between them is that they are related. However, the uncle and aunt are not as deeply invested in their nephew's future as his parents are. In their relationship he may have the freedom to express his true wishes and desires and by doing so come to understand himself.
