Donna is a grouchy and sensitive 11-year-old tomboy who doesn't like to be touched; if anyone touches her, she punches them. Her surly attitude mainly comes from being unhappy about her life and that her parents are divorced. Initially, she is also very snide towards Grace Conrad, who acts the same way towards her at first, but over time, Donna develops a more friendly personality. At the end of the movie, she shares a kiss with Charlie Goldfinch.
