How does Betsy Byars use imagery in The Summer of the Swans?

Imagery:

“It was as if her life was a huge kaleidoscope, and the kaleidoscope had been turned and now everything was changed. The same stones shaken, no longer made the same design.”

“I have cried over myself a hundred times this summer, she thought, I have wept over my big feet and my skinny legs and my nose, I have even cried over my stupid shoes, and now when I have true sadness there are no tears left.”
