There are many animals on the world. But I`d like to tell you about my favourite one. it is wolf. I`m really admire for its beauty and grace. There are many kinds of wolves, which have differents in their appeance, for example in colour. But I`m like this animals not only by its appearance, I`m wonder for their intelligance and devotion to their pack. Once, I saw wolves`s hunting on TV. It was emazing! I marvel their speed and endurance. They can silently stalk prey like a shadow.
If someone`ll ask me whether I would like to become in the next life, I`ll have chosen wolf.
