Well! thought Alice to herself. After such a fall as this, I shall think nothing of tumbling down-stairs! How brave they'll all think me at home! Why, I wouldn't say anything about it, even if I fell off the top of the house! {Which was very likely true.}
Alice reflects on her recent tumble and feels surprisingly unbothered by the fall. She considers how her attitude might change once she's back home, imagining how brave she’ll seem to her family after such an incident. Her shrugging confidence shows her current perception of the fall as less frightening than it might be perceived by others.
She even humorously suggests that she wouldn’t mention falling—even from a great height—highlighting her whimsical and fearless character. This playful outlook is typical of Alice's curious and adventurous personality, as she navigates the strange and unpredictable worlds described in Lewis Carroll's stories.
