The Tone Of The Chapter Is Whimsical And Affectionate, Tinged With Marilla'S Strict But Caring Attitude Toward Anne, Who Displays Her Usual Exuberance And Imaginative Spirit.

Anne Shirley looks forward to the upcoming Sunday-school picnic with great excitement while Marilla admonishes her for tardiness and daydreaming. Despite her initial display of strictness, Marilla shows affection towards Anne by agreeing to bake a basket for the picnic.

Chapter XIII unfolds on a languid August afternoon, with Anne Shirley outside conversing animatedly with Matthew Cuthbert instead of doing her sewing as instructed by Marilla. When reprimanded for her tardiness, Anne's enthusiasm overshadows her disobedience as she shares the news of a forthcoming Sunday-school picnic. She pleads to attend, concerned about going without a basket of food. Marilla reproaches Anne for her lack of punctuality, yet permits her to attend the picnic and promises to bake a basket for her, a gesture that elicits an affectionate response from Anne. Through the preparations and Anne's imaginative musings about her play spots and Diana, Marilla reflects on Anne's fanciful nature and her own hidden pleasure in Anne's affectionate outbursts.
