Story:
A long time ago, there was a frog living in a deserted well. It had never jumped out of the well, and with plenty to eat and drink, it felt quite content.
One day, it curiously asked a passing sea turtle how vast the sky was. The sea turtle described how incredibly vast the sky was, but the frog couldn't comprehend what the sea turtle was explaining.
It firmly believed that the sky was only as big as the well's opening and that the sea turtle was just joking with it.
