What is the simile in the breadwinner?

In "The Breadwinner" by Deborah Ellis, a notable simile is when Parvana's life is compared to a bird trapped in a cage, which effectively conveys her sense of confinement and lack of freedom under the Taliban regime. This comparison highlights her struggles and the limitations placed on her due to societal restrictions. Such vivid imagery emphasizes her yearning for liberation and the desire to support her family in a challenging environment.
