One day, a rabbit, a turtle and a squirrel were reading a book. At this time, the little hedgehog came and sat with the rabbit, but as soon as the little hedgehog touched the rabbit, he was stabbed and shouted. The hedgehog said, "Excuse me, please sit down." The little hedgehog just wanted to leave when the little turtle stopped him and said, "Don't go, let's sit together." The hedgehog said, "But I will stab you." The little turtle said, "My shell is very hard. You won't stab me. " After the little turtle finished reading, everyone began to read again.
