What do we learn about the aunt from the first paragraph

The novel opens with Aunt Polly searching for Tom Sawyer, the young protagonist of the novel who, along with his younger brother Sidney, was sent to live in St. Petersburg, Missouri, after his mother's death. After hearing no answer to her calls, Polly finds Tom eating out of the jam closet. Tom escapes Aunt Polly's beating by diverting her attention, leading Polly into a tirade against Tom's irreverent ways.
