The details from the text that supports the idea that Miss Emilie thinks Lily should be working hard while her mother does not are "I had assumed you would have come here straight from school since we only have a few days to prepare for your audition," Miss Emilie said, tapping her foot impatiently.
"Lily, sweetheart, I am worried that you are working much too hard for this audition," her mother said. "I wish you would find some perspective and realize that ballet is not the most important thing in the world."
Lily' mother and Miss Emilia had contradicting opinions regarding Lily's ballet practice. Lily's mother felt that Lily was putting too much of effort for the audition while Miss Emilie wanted Lily to put more effort so that she could make it through the audition.
