# Rabbits on the Roof — Who’s Counting? #flashfiction

This week at the Carrot Ranch, Charli Mills challenged writers to In 99 words (no more, no less), write a story about a rabbit on the roof. Or many rabbits. Why are they there? Explain the unexpected, go into any genre. Go where the prompt leads!

As I mentioned in my comment on Charli’s post, all I could think about was the Fibonacci Rabbit Problem.

I wrote about the Fibonacci number sequence previously in a post called Counting on Daisies.

In the Fibonacci sequence, each number is the sum of the two preceding numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and so on.

As the sequence progresses, the numbers get exponentially larger, not unlike the numbers succumbing to the dreaded virus that engulfing our world at the moment.

The number sequence occurs naturally in many situations; for example, in bee populations, in spirals of snail shells, in leaves on plants and petals on flowers.

But who was Fibonacci, why does he have a number sequence named after him, and what is the problem with rabbits?

Fibonacci was the Italian mathematician who introduced the Arabic-Hindu system of numbers and arithmetic (the numbers we use) to the Western World in the 12th Century.

Fibonacci wasn’t his real name. He was really Leonardo Bonacci. His famous book Liber Abaci was handwritten, long before the era of the printing press (let alone computers and indie publishing).  A couple of centuries later, some students reading his tome, misread what he had written (‘filius Bonacci’ meaning ‘son of Bonacci’) as Fibonacci and that’s how he’s still known today.

Fibonacci (Leonardo Bonacci) wrote about the number sequence that now bears his name in his book Liber Abaci. He explained the sequence using an example often referred to as The Rabbit Problem. The problem involves rabbits breeding profusely. While the situation described isn’t necessarily accurate, it is entertaining and helps us get the picture.

A beautiful picture book by Emily Gravett, also named The Rabbit Problem, is a fun way of introducing the concept to children. Set on Mr Fibonacci’s farm, the rabbits multiply each month for a year according to the number sequence. However, each month, new problems for the rabbits arise.

If you’re interested in finding out more about Fibonacci’s numbers, I highly recommend this video by mathemagician Arthur Benjamin.

But now for my story in response to Charli’s challenge. Perhaps it has an underlying message suited to these troubling times. Maybe you’ll see it too. If not, I hope it’s just a fun story that you enjoy.

What Rabbits?

“Wassup?” He knew something was when she stopped rocking.

“Nothin’.” She continued rocking.

“Musta bin somethin’.”

“Nah. Thought I saw a rabbit on that roof, is all.”

“I ain’t never seen no rabbit on a roof.”

“You ain’t never seen nothin’.”

“What?”

“Thought there was two rabbits on that there roof.”

“That’s crazy.”

The rabbits multiplied, but she never stopped rockin’ and she never said nothin’.

One day, he stopped.

“Shhh. I hear somethun.”

“What?”

“Sounds like …”

A multitude of rabbits exploded from the roof, landing all around, even in their laps.

“What?”

“Nothin.”

They kept on rockin’.
