Brother Rabbit and Brother Goat
Brother Rabbit had four carrots. He was very hungry. He wanted to eat the carrots. But then he thought that his friend Brother Goat was hungry too. So he ate only two carrots. He wanted to give the other two carrots to Brother Goat.
He took the two carrots and ran to Brother Goat’s house. Brother Goat was not at home. So Brother Rabbit put the two carrots on the table and ran away.
When Brother Goat came home and saw carrots on the table, he thought: “Oh, what good friends I’ve got! And I want to be a good friend too. I think that Brother Rabbit is hungry.”
So Brother Goat ate only one carrot, took the other carrot and ran to Brother Rabbit’s house.
Brother Rabbit was not at home. Brother Goat put the carrot on the table and wrote a letter, “Dear Brother Rabbit! This carrot is for you.
Love from Brother Goat.”
When Brother Rabbit came home, he saw the carrot and the letter on the table. He read the letter, ate the carrot and thought, “Oh! What good friends I have got!”
