NaPoWriMo's Day 6 prompt 'focuses on the use of concrete nouns and specific details, using the idea of “putting a dog in it.”' Here's a poem with solid images on the theme of anxiety.
A sprinter on the starting blocks, waiting for the gunshot.
A free-diver, testing that lungful of air, plunging deeper.
Gripping an overhead pole, dangling, holding,
A balloon slowly being inflated.
A dog in an unfamiliar house, reluctant to sit or lie.
That guy at the back of the bar, drunk, eyes locked on you.
Waking up to the sound of your ringtone.
Realising, at 80mph, you're really too tired to drive.
Waiting for your boss to mention your lateness, again.
All of this expelled by your fist, slamming concrete-like,
into the weighted punch bag.
