Croc, a poem

Here's a lesson from the crocodile,
who greets you with a habitual smile.
Hot or depressed or weary from labors,
he still finds a way to show kindness to neighbors.

So now my fist too mutates to a false fin.
I show just enough of my chinny chin grin
(without the tiniest hint of pretension)
to hide, with all mankind, my natural intention.
