I've heard it said that, were you to gain the ability to fly, you could often fly around and not worry about being seen. People so rarely look up that the odds are good that you could go unseen without any powers of invisibility.
Whether or not it's true, I do find that I'm usually looking anywhere but up. However, whenever I do glance skyward, I appreciate it. There's always a cool cloud formation or a gorgeous moon or a starry night or trees blowing around, being trees.
When a writer tells me that they're stuck, one of my canned responses is, "Have them look up. What did they see?"
