In the dialogue, a character expresses concern about their mother's potential arrival while someone important is away. The suggestion is to hide in the hay-loft as a way to avoid detection. This highlights the character's anxiety about being discovered and the lengths they might go to maintain a secret.
The recommendation also implies a level of confidence in the mother's judgment, indicating that if she were sensible, she wouldn't take any drastic actions to find the absent person. This creates a humorous contrast between avoidance and the mother's supposed logic, emphasizing the tension and playful worry present in the scene.
