Step-by-step explanation:
Lady Waldemar describes her voice as being "impaled" when reading Aurora's poetry in order to emphasize the pain reading Aurora's poetry caused her. In this context, "impaled" suggests that Lady Waldemar found reading Aurora's poetry to be a painful and difficult experience, as if her voice was being pierced by a sharp object. This description suggests that Lady Waldemar did not enjoy reading Aurora's poetry and found it to be a challenging task.
