Introduction:

In the story, the author recognizes Mrs. Dorling based on certain observations and interactions. Mrs. Dorling is a woman who comes to the author's door inquiring about a lost dog. Let's explore how the author identifies her as Mrs. Dorling.

Observing the woman:

When the author opens the door, he notices a middle-aged woman with a worried expression on her face. This initial observation provides the author with some clues about her identity.

Verifying the woman's identity:

1. Physical appearance: The author compares the woman's appearance to the description given by Mr. Dorling, who had described her as a middle-aged woman with a worried expression. The woman at the door matches this description, strengthening the author's belief that she is Mrs. Dorling.

2. Knowledge of the lost dog: The woman mentions that she is looking for a lost dog, which aligns with the reason for Mrs. Dorling's visit as mentioned by Mr. Dorling. This further supports the author's recognition of her identity.

3. Recognition by the dog: The author's dog recognizes the woman and shows signs of familiarity and happiness upon seeing her. Dogs have a keen sense of smell and memory, and the author's dog's reaction indicates a previous acquaintance with the woman. This recognition by the dog helps confirm her identity as Mrs. Dorling.

4. Confirmation from the woman: The woman confirms her identity when the author directly asks if she is Mrs. Dorling. Her response, either verbally or through acknowledgment, serves as a final confirmation.

Conclusion:

By observing the woman's physical appearance, her knowledge of the lost dog, the recognition by the author's dog, and her own confirmation, the author is able to recognize that the woman at the door is indeed Mrs. Dorling. These details provide sufficient evidence for the author to make an accurate identification.
