Why did the narrator of the story want to forget the address?

The narrator went to the house of the lady who had kept many valuable items of her mother during the war days. The address of the lady helped her in searching out the house of the lady. But now she wanted to forget the address as after visiting the house of the lady since she found how the belongings of her mother were kept in a strange manner. They had lost all their emotional value for the narrator. The narrator now lived in a small rented room. She had no place to keep all these things. The lady treated her very insolently. She even refused to recognise her. She did not let her come into the house. That was why she wanted to forget that address.
