A butcher watching over his shop is really surprised when he saw a dog coming inside the shop. He shoos him away. But later, the dog is back again. So, he goes over to the dog and notices he has a note in his mouth.
Along comes a bus. The dog walks around to the front, looks at the number, and goes back to his seat. Another bus comes. Again the dog goes and looks at the number, notices it's the right bus, and climbs on.
There's no answer at the house, so the dog goes back down the path, jumps up on a narrow wall, and walks along the perimeter of the garden. He gets to the window, and beats his head against it several times, walks back, jumps off, and waits at the door.
