There's a children's book out called Fish is Fish. It is a fable about a fish who is friends with a frog. The fish wonders what things are like on land and the frog explains and describes the different animals on land. All the fish can do is imagine a fish with the same description.
The frog describes a bird and the fish imagines a fish with wings.
This image moved me. I hope to keep the appreciation of my lack of perspective all the time.
