Character sketch lutkin's mother

The hack driver told the narrator that Lutkins’ mother was a terror. He told him that she was about nine feet tall and four feet thick. He told him that once he had taken a trunk for her at her farmhouse. She almost had taken his skin off because he had not treated the trunk like a box of eggs. He said to him that she was as quick as a cat. If she had heard from anywhere that someone had been looking for her son, she would have been more dangerous. He made the narrator more frightened to tell that facing such a dangerous lady would be very risky.
