"What's that?"

It's a childish question, really.

"There it is again! Did you hear it?"

That's more like it.

"No…"

Of course you didn't.

"Do you see something?"

Of course they don't.

"No."

I'm just a trick of the eye.

"It's probably nothing."

That's right.

"Yeah. It's nothing."

They won't see me coming.
