This is the first paragraph of the story:
She flicked her wrist neatly out of Doctor Harry’s pudgy careful fingers and pulled the sheet up to her chin. The brat ought to be in knee breeches. Doctoring around the country with spectacles on his nose! “Get along now. Take your schoolbooks and go. There’s nothing wrong with me.”
The reader can tell, just from this short paragraph, that Granny Weatherall is someone who does not want to be seen by her doctor, does she?
We can tell that she is quite grumpy and self-righteous, as well. Her dialogue to the doctor indicates she is mocking the doctor, calling him a schoolboy because he is young. She does not see him as being qualified to examine her because he is so young.
The fact that she flicks her wrist away from the doctor indicates that she is in no mood to be "handled" by the doctor. She has what I call "attitude"!
