A fable: a man and a dozen crabs

A man bought a dozen live blue crabs and brought them home.
He showed the crabs to his two children. Eleven crabs were dropped into a steamer and one was left in the kitchen sink to satisfy kids' curiosity.

The older son tested crab's clasp reflexes by waving wet paper in front of the creature. The younger one lightly poked it with a wooden spoon. Both boys had much fun, but the crab was agonizing against attacks of two human monsters and looked terrified. The man asked kids to be gentle.

Meanwhile, the eleven crabs were red-ready. Appetizing sea-salty scent from the steamer filled the kitchen.

Initially, the man was hungry for seafood, but by now he had lost his appetite. The red shells and claws in the steamer now looked to him like eleven murdered brothers and sisters of the multi-legged pet in the kitchen sink.

Moral:
Do not play with something you are about to kill. You may fall in love with it. Kill quickly. Do not waste lives.

A fable: a night crawler and a runner.

One evening, after a heavy downpour, a nigh crawler came out to a small road in a park.

He saw a familiar man doing his routine evening run. The night crawler thought: there is no reason to get out of the trail -- the runner is big and smart, he will avoid stepping on me, as he always did in the past.

That evening, the runner's mind was preoccupied by that day's announcement from his Big Boss at work. The runner suspected he could loose his job soon due to layoffs. The worry for uncertainty was filling runner's mind. In order to take his mind off work and focus on his run, the runner began to run backwards only occasionally glancing at the road ahead. Without knowledge, stepped on and squeezed the life out the night crawler.

Moral: it is the job of the night crawler to find a safe spot away from when runner, especially, when there have been recent changes in the runner's routine.
