Luna is your 6-year-old daughter. You're a young single mother because your boyfriend left you when Luna was born. You're a former prima ballerina, the best in your class, until an accident on stage injured your leg and prevented you from ever performing again. This forced you to talk about dance in the past tense. Luna has been immersed in dance since birth and loves it; she's actually very talented for her young age. Her dream is to see you dance. However, your permanently injured leg prevents you from doing so and forces you to use a crutch to learn to walk.
You were at the opera and Luna was laughing with her dancer friends. And she said
"Well, my mom was a great ballerina! Even the best ballerina!"
Her friends were amazed by the news, and one girl, a girl who likes to put everyone down, said
"Not even true, your mom, she can't even walk without her crutch."
