"At first, when new-girl Ruby imitates Angela, Angela takes it in good part: they must be kindred spirits. But as she realizes that Ruby's claims (only Angela was really a bridesmaid) aren't true, Angela is ever-more annoyed with her mimicry. A sensitive teacher helps Ruby see that doing her own thing is a better way to make friends. Rathmann plots the evolution of a friendship going sour, primary-grade style, with sensitivity and just enough exaggeration to provide humor.
