How does Frank B. Gilbreth use imagery in Belles on Their Toes?

Imagery:

"Well, what she had feared had happened, and tears would not wash out a word of it."

"If the only way to enter a man's field was the kitchen door, that's the way she'd enter" (Chapter 10, p. 101).

"We wound up the song standing around the piano, pushing as close to Mother as we could. Frank did his best to sing bass, but all of us knew something was missing from the harmony" (Chapter 12, p. 127).
