I'd been sitting on the park bench reading by book for a few minutes when it started bugging me. I swatted at it a few times but each time, it dodged my book.

"I wouldn't do that if I were you."

My attention snapped to my left. To the man who'd just sat next to me. He had a wild look about him. Unkempt beard, messy hair, eyes that darted from side to side as if trying to spot a predator.

"Do that? Do what, exactly? I'm just reading my book."

"It's not really a fly. If you swat it, they'll fine you and send two more."

"Of course it's a fly."

"It's not y'know."

"Well what is it then?"

"A drone. A little microcamera in a metal insect form. They're everywhere. Watching everyone."

"Seriously? Come on, it's a fly. OK, if it's a drone, who sent it?"

"They" he glanced about in alarm. "They're everywhere. Don't swat them. I've said too much."

He stood and bolted out of the park.

I sighed and shook my head. "Bloody loony."

And then... Wham! "Got you, you little bugger."

I looked at the mess on the back of my book and patted my pockets for a tissue, sighed and stood to return home. "Typical."

The odd thing is, I'm pretty sure a couple more flies started buzzing me as I walked down the street.
