How does Scout describe Calpurnia?

From the text:

Calpurnia was something else again. She was all angles and bones; she was nearsighted; she squinted; her hand was wide as a bed slat and twice as hard. She
was always ordering me out of the kitchen, asking me why I couldn’t behave as well as Jem when she knew he was older, and calling me home when I wasn’t ready to come. Our battles were epic and one-sided. Calpurnia always won, mainly because Atticus always took her side. She had been with us ever since Jem was born, and I had felt her tyrannical presence as long as I could remember.
