It is a lesson in how peculiarly limited a child’s sight is: he sees only what he can see. Only later does he learn to link what he sees with what he already knows, or has imagined or heard or read, and so come to make perception serve inference. During my childhood I kept hearing about the Cypress Hills, and knew that they were somewhere nearby. Now I see that I grew up in them.
This is from Wolf Willow by Wallace Stegner. This is also why departing one’s childhood’s home obliterates return.
