Haughty: adjective: having or showing the insulting attitude of people who think that they are better, smarter, or more important than other people

From the story ” A Rose for Emily”, ” ‘I want some poison’. she said to the druggist. She was over thirty then, still a slight woman, though thinner than usual, with cold, haughty black eyes in a face the flesh of which was strained across the temples and about the eyesockets as you imagine a lighthouse-keeper’s face ought to look.”

Now I understand that when Emily asked for the poison, she had a very dominating look in her eyes so that she won’t be questioned about buying the poison.
