The adoption plane (a flat or level surface) shows the adoptee between the other two members.
This better represents the truth behind adoption and its members. It can also display the way many adoptees feel like the center of a tug-of-war between their loyalties to the adoptive family and their longing to know their heritage and blood. By adjusting the image, the plane can illustrate an adoptee's emotions or state of mind, moving back and forth between the two families.
