The black cat can't remember why it is a black cat, and it can't remember why it is in the cage of the pet shop. It doesn't like to bark, doesn't want to walk, just lies quietly in the corner, no one will buy a "dumb cat", and it is unlucky to buy a black cat. Until one day, the pet shop came to a president, who looked rather cold. The female shopkeeper was flattering and flattering. But the black cat suddenly opened his eyes, and the president took a fancy to it at a glance.
