Read the passage.
Her hair was like curly silk and she had a delicate little nose which seemed to be disdaining things, and she had large laughing eyes. All her clothes were thin and floating, and Mary said they were "full of lace." They looked fuller of lace than ever this morning, but her eyes were not laughing. They were large and scared and lifted imploringly to the fair boy officer's face.
"Is it so very bad? Oh, is it?" Mary heard her say.
"Awfully," the young man answered in a trembling voice. "Awfully, Mrs. Lennox. You ought to have gone to the hills two weeks ago."
The Memsahib wrung her hands.
"Oh, I know I ought!" she cried. "I only stayed to go to that silly dinner-party. What a fool I was!"

All her clothes were thin and floating.
She wrung her hands.
She stayed in the cholera-infested area so she could attend a dinner party.
