He hasn't seen a traffic jam,
like this in many years.
He should have stayed home,
with his dog and few cold beers.
His car hasn't moved in minutes,
he's on the verge of showing rage.
Nothing will stop him now,
not even an old hard lonely cage.
The noise began suddenly,
when he let his car horn fly.
Expressing his displeasure,
he wasn't very shy.
Then he began to argue,
with any soul that dared.
He turned flush red with anger,
as his big old nostrils flared.
He jumped out of his car,
and began to wave his cane.
Grandpa forget he was 91,
and all his old age pain.
Finally someone calmed him,
and asked for seven sixty-five.
Grandpa paid for his burger and fries,
and slowly began to drive.
I would turn this into an animated short (without actual poetry) mainly shot from within the car, which makes use of camera angles to avoid revealing the man's true identity and where he actually is until the final moments e.g. via close-ups of parts of his face and body.
I could enforce the annoying traffic jam aesthetic further via rainfall, blurring the scenery in front of him and allowing for a matte painting or low poly models to replace the other cars.
I could also avoid having to fully model the fast food employee if necessary, via only their hand and arm being seen. The ending could be shown in a long shot, revealing the drive thru and other aesthetics such as a zimmer frame strapped to the car roof.
