Ada Potato (1987)
Ada takes up the violin and enjoys playing, but her pleasure is spoiled when a group of older children makes fun of her. She and her friends solve the dilemma. In real life, I was called “Judy Patootie” when I ran through the tunnel clutching my viola. My mother wouldn’t let me quit playing the instrument, although I begged and pleaded.

“A welcome, non-didactic treatment of a problem familiar to many children.” --Horn Book
