Susan Shapiro is the best friend of Molly McIntire. She is described as a "cheerful dreamer." She is often hungry and in awe of anything fanciful and glamourous. She is not as practical as Linda or as much of a schemer as Molly, though she can come up with fanciful ideas such as when she suggested that Molly get a home perm to make her hair curly to perform as Miss Victory. She is very honest with herself and her friends (for examples she notices when Molly is jealous of Alison right away). She always speaks her mind, for good or bad.
