I'm an inadequate filter
This isn't a metaphor about a physical filter
It's a metaphor about a metaphor
I slip all heavy elements into speech
Gold too fine the dross is leached
And leaking meekly speed beseeching
won't evolve my beak
An inadequate filter
Etiquette folder
shifting morphologic solder
As the meaning goes in these shifting themes^^^^
So is it with microscopic memes
Which generate a field of dreams.
