“Nuts,” said the Martian. “You people got rocks in your heads, that’s what accounts for your superstitions.” — Fredric Brown

Still sitting there, still looking up in the tree.

At something that isn’t there? Luke wondered.

Or at something that isn’t there for me but is there for him, and which of us is right?

And he thinks that I don’t exist and I think I do, and which of us is right about that?

Well, I am, on that point if no other. I think, therefore I am.

But how do I know he’s there?

Why couldn’t he be a figment of my imagination?

Silly solipsism, the type of wondering just about everybody goes through sometime during adolescence, and then recovers from.

But it gives to wonder all over again when you and other people start seeing things differently or start seeing different things.

A new racket, probably. A depression breeds rackets as a swamp breeds mosquitoes.
