You're sitting with a friend and you're talking about what you see. It's a field, it's a bay, it's a city. As you talk, it becomes clear that what you see is not what she sees. You keep talking about different things, sort of trusting that your friend simply sees something you'd see if you were in her place. Because masts, trees, rocks, clouds, and cars block your vision, but from where she sits no cloud or giant is in the way. You move over a bit and you say, "Oh! Yeah!"
Everything is a little different for having seen what you couldn't, but you shift back and now you're right where you were.
