Sense Sonnet - Chiller

Family Recycle

His son was only two years old,
But had a vocabulary
Of an adult, and one day told
His Dad that his son used to be
His Dad's grandfather, coming back
Through the portal, and now was here
On a reincarnated track,
The grandfather did reappear.
In fact his grandfather had died
One day before was born his son.
Dad asked his son, his son replied
How the grandfather's death was done.

Dad's son slapped the top of his head.
Cerebral bleed made Granddad dead.
