The postman inside the house

She's a girl who loves going for walks, but her interests extend to everything in the world. Sometimes packages arrive for her mother, who works from home. After her mother receives them at the front door, "Okay, I'll leave it to you again today." "Yes! Leave it to me!" It's the girl's job to carry the mail from the front door to her mother's office. She's a cute postal worker who delivers with a smile today as well.
