Bird's nest

Once upon a time, there was a grandfather living in a small house under the mountain. One day, the grandfather walked out of the house with a hat and walked around, seeing a small bird tremble on the branch. The old grandfather disregarded himself and took off his beloved straw hat and picked it up with both hands. He said, "The bird asks you to fly into the straw hat! The straw hat will bring you warmth." When the bird heard the words of the old grandfather, he immediately flew into the straw hat. The grandfather thought that if the straw hat was placed on the tree, the snow would be everywhere, the straw hat would be ice, and the bird would still be frozen. So the grandfather took the straw hat back. Since then, the grandfather and the bird live together, the grandfather is very happy every day, the bird did not expect to have such a happy home.
