My poem, Turtles, was originally published in blackmail press. For other Tuesday poems, click here: 
Turtles
Some things aren’t meant to be understood:
Like electricity or war
You know they’re going on somewhere
But it’s best not to think about it
It could make your hair curl
Ann explains the turtle theory of light:
Behaving neither like a wave nor a particle
Light is more like a great string of turtles
Each holding the next one’s tail in its mouth
Like the pin in a grenade
What they do when they get to a light switch is
Anybody’s guess

This is lovely, and also a little bit creepy. Thanks!
“Light is more like a great string of turtles / Each holding the next one’s tail in its mouth”
I love that part, and imagine it as a micro-universe within a ray of light. Like Terry Pratchett’s “Discworld” series which I absolutely adore.
The ending, tied in with the second line of the poem, made me think of war as a chain reaction.
Oh whew. The lyricism of this poem pulled me straight in… I have a very soft spot for turtles so was not prepared for the shock of the third last line. The environmentalist/pacifist in me wants to beg you to remove the words ‘like a pin in a grenade’. My feeling is that the poem works even more splendidly without them? (with respect, Janis, and apologies for my candour.)
Thank you… Claire
Thanks for your comments, folks. I do have to thank Ann McCrone for coming up with the whole ‘light as a string of turtles’ concept.
