This is the parable of the prodigal son: consider reading it and making them guess

Feeling footloose and frisky, a feather-brained fellow
Forced his fond father to fork over the farthings.
And flew far to foreign fields
And fabulously frittered his fortune with faithless friends.
Fleeced by his fellows in folly, and facing famine,
He found himself a feed-finder in a filthy farmyard.
Fairly famishing, he fain would've filled his frame,
With foraged food from fodder fragments.
"Fooey, my father's flunkies fair far finer,"
The frazzled fugitive forlornly fumbled, frankly facing facts.
Frustrated by failure, and filled with foreboding,
He fled forthwith to his family.
Falling at his father's feet, he forlornly fumbled, "Father, I've
Flunked, and fruitlessly forfeited family fellowship favor,"
The farsighted father, forestalling further flinching,
Frantically flagged the flunkies.
"Fetch a fatling from the flock and fix a feast."
The fugitive's fault-finding brother frowned
On fickle forgiveness of former folderol.
But the faithful father figured,
"Filial fidelity is fine, but the fugitive is found!
What forbids fervent festivity?
Let the flags be unfurled! Let fanfares flare"
Father's forgiveness formed the foundation
For the former fugitive's future fortitude!
