This passage describes Alice's frustration and displeasure at a rude and unpleasant tea-party she attended. Feeling overwhelmed by the rudeness, she decides to leave in disgust, while the Dormouse falls asleep and the other guests ignore her departure. Alice looks back, hoping someone will call her back, but they remain indifferent, even when they attempt to put the Dormouse into a teapot.
She expresses her strong dislike for the experience, declaring, It's the stupidest tea-party I ever was at in all my life!
As she walks away through the woods, she firmly decides she will never return to that place, emphasizing her displeasure with the entire event.
