There was a Granny who had a brace of flying ducks. They spent most of their time sitting and resting on a nearby shed watching the neighbourhood. Every now and then Granny would catch a duck for a dinner. She threw duck food on the ground then waited for them to come closer until she was able to catch one after a short chase.
Years passed and Granny no longer had the strength to chase ducks. But she had an idea. She pulled a few feathers from each duck tail to stop them flying away from her. It solved the problem, but what happened next was totally unexpected.
The new generation of ducks born from non flying parents did not even try to fly. They had all the feathers needed to be able to fly but no one to show them that they could. The best they could do with their wings was merely correct their balance or fly just above the ground, which felt more like fast running. They led their lives in a flat world never being aware of the true potential of their wings.
