"Front" is a place in our head that's like a doorway right through the shared-body's eyes. Front was one of our first internal landscape interfaces that we recognized.
We have early poems that refer to front as a door or window, and to the inside of our head being a deeply shadowed room. When (external) people look deeply into our eyes, they are looking through the doorway and into us.
"Front" gives way to other terminology we've always used, such as "in Front" or "Fronting" for someone inside who is looking directly through our eyes to external reality, and "Front Room" which is the internal room where the "Front" doorway is. The person who "is front" or "is fronting" is the one currently in the doorway.
