Anne loves having pretend tea parties by herself. She even decorates her room with branches and colorful leaves for the occasion. Marilla Cuthbert, who adopted Anne in the last year, wishes Anne would act a little more sensibly. One day, Marilla comes up with a plan to keep Anne out of mischief — Anne can host her very own tea party and invite her kindred spirit, Diana Barry! Anne is thrilled, and sets out to host the most lovely and grown-uppish tea party she can muster. But when she makes Diana sick by accidentally giving her the wrong drink, Diana's mother is furious. Can Anne be forgiven? Will she ever be allowed to play with Diana again?
