Beatrice Quimby's biggest problem was her little sister Ramona. Beatrice (or Beezus, as everyone called her) was very patient with Ramona but eventually she got so exasperated that she decided she did not like Ramona at all. Not one little bit. Tooting one note of her harmonica for hours, locking Henry Huggins' dog Ribsy in the bathroom, baking her rubber doll into Beezus' birthday cake—how could a four-year-old be such a pest? Beezus knew sisters were supposed to love each other all the time, like Mother and Aunt Beatrice. But with a sister like Ramona, it seemed impossible!
