I hope you like this. It is an attempt at a none-rhyming more modern style.
I sat and ate on a park bench
sun and shadow dancing overhead
I was daydreaming as I chewed
when movement turned my gaze outward.
A passing blackbird caught my eye
as he pranced along an invisible path
his quick movements caused me to smile
A passing whim cause me to toss a crumb
I watched it jump back with a start
then leap forward with greed avidity
Several fragments followed the fist
As I passed a contented lunch
by giving some of it away
