The whole world is my well

A frog born and lived in a well for a long time. One day another frog that lived in the sea came and fell into the well.
Well, one day another frog that lived in the sea came and fell into the well.
“Where are you from?”
“I am from the sea.”
“The sea! How big is that? Is it as big as my well?” and he took a leap from one side of the well to the other.
“My friend,” said the frog of the sea, “how do you compare the sea with your little well?”
Then the frog took another leap and asked, “Is your sea so big?”
“What nonsense you speak, to compare the sea with your well!”
“Well, then,” said the frog of the well, “nothing can be bigger than my well; there can be nothing bigger than this; this fellow is a liar, so turn him out.”
That has been the difficulty all the while, we all are sitting in our own little well and think the whole world is my well.
