In this passage from Alice's Adventures in Wonderland, Alice's mindset has shifted significantly. She has become so accustomed to unusual and extraordinary events that ordinary life now feels boring and uninteresting to her. Her perception has changed because she has been exposed to so many out-of-the-ordinary experiences that she finds normal life dull.
Lewis Carroll captures Alice’s sense of disappointment with the mundane by highlighting how her expectations have altered her view of reality. The quote reflects her struggle with the transition from a world of wonder and surprises to the ordinary, which now feels lacking in excitement and meaning for her.
