What might work

A poem, or something that might work as a poem, in two parts I'd written a year or so ago and found under a pile of papers this morning--

 1

Nothing really works.

Cars work but they foul the air.

Airplanes work most of the time but sometimes they fall out of the sky and crash, though not as often as cars crash.

2

What does work?

Going nowhere works, and walking there if your feet don't hurt.

Or riding a bike instead of walking, especially when you know where you're going.
