She generally gave herself very good advice {though she very seldom followed it}, and sometimes she scolded herself so severely as to bring tears into her eyes; and once she remembered trying to box her own ears for having cheated herself in a came of croquet she was playing against herself, for this curious child was very fond of pretending to be two people.
In this excerpt, the character is portrayed as giving herself wise advice, although she rarely follows it. She is notably harsh on herself, often scolding herself to the point of tears. Her childhood curiosity and playful nature are evident, as she once tried to physically reprimand herself for cheating in a game she was playing alone.
This passage also highlights her imaginative and playful personality, as she enjoys pretending to be two different people. Her tendency to engage in such whimsical games reflects her creative and curious character, which is central to the fantastical world she explores in the story.
