Daydreaming, I put a foot wrong, my ankle folded and I flipped into the air. Using my Special Cat Self-Protection Skills I span (in slow motion of course) so I landed on my left and not my right*.

A moment later, I am flat on my back, yelling a mouthful of obscenities at the sky and running a checkpoint on my body:

Hip? Seems not to have come out.
Thigh bone? Still there. Phew.
Wrist? Hmm. Wait and see.
Ankle? Ouch. Twisty. Ouch. Ouch.

A face appears over me, with a look of concern. "Are you OK?" it asks.

"I don't think so."

"Oh, OK." And the face vanished.

Baffled, I'm still on the ground. Another person comes along, "Are you OK?"

"No. Not really."

"Oh, OK. You've broken your phone."

And he vanished too.

* My balance is so screwy I've developed a weird reflex which spins me around like this because I'd rather break my arm than risk wrecking another damn hip replacement. I'm told it's quite something to see. Falling over in the street is far from the worst thing ever to happen, but, it scares the hell out of me for the first seconds after I hit the tarmac.
