Is the sentence from the story about the lion and the mouse or from some other story?
ONCE on a time there was a hare who was frisking up and down under the greenwood tree.
Woken from his nap, the lion laid his huge paw angrily on the tiny creature to kill her.
Hare stretched himself out alongside the road and fell asleep, thinking, "There is plenty of time to relax."
Then she lay down in the third bed and it was just right.
"Please let me go and some day I will surely repay you."
When spring came they longed to travel up to the mountains to eat the lush sweet grass.
Some days later, the lion fell into a trap and found he was caught fast in a stout net.
She began nibbling and nibbling until the rope broke.
Before they left, their mother told them " Whatever you do , do it the best that you can because that's the way to get along in the world.
Don't forget: even the smallest friend is worthwhile!
