Bon voyage

A sparrow and his hen
With kids, happy in their nest
The birds all of a sudden
Decided to cross the sea
To check what's there to see

For months they tried
Flexed their wings
Exercised to build them stout
Not with their winsome wings
But with the disobedient waves
They found them a bit unsound
The water roared too wide
They felt tiny to cross the side

The two pondered for long
The yearning to leave was strong
Their nestlings have grown up,
Gone out of sight
They wouldn't know how to
Make the flight
They were about to give up
On the trip
When they perched on
A sailing ship
