Buster Casey is Lily Casey Smith’s brother, who is one year younger than her. When he is nine years old, he is saved by his older sister from drowning at a flash flood. He is described as a
“rabbity little kid, but he had an irresistible smile, and maybe to compensate for Dad’s speech impediment, he was one of the fastest and smoothest talkers in the county” (p. 18, ll. 26 - 28).
Being the only son of Daisy Mae and Adam Casey, Buster is admired by his mother
“She completely doted on Buster. […] She was always telling Buster there were no limits on what he could become – a railroad magnate, a cattle baron, a general, or even the governor of Texas” (p. 18, l. 25 - p. 19, l. 2)
In 1913, he is is sent to a boarding school near Albuquerque, which he leaves after he has finished the eighth grade. His parents would like him to go to High School, but Buster is not
as interested in education
as his sister, Lily:
“Buster wasn’t interested in high school. He knew enough math and reading and writing to run a ranch, and he didn’t see much point in picking up more knowledge than that. Cluttered the mind, in his view” (p. 52, ll. 2 - 5)
He falls in love with Dorothy Clemens and in 1918, they marry
. It was a good decision since “he was always a little unmotivated, and if he was going to run the ranch with any success, he’d need someone determined and hardworking like Dorothy besides him” (p. 52, ll. 10 - 13).
Dorothy and Buster are going to have two children.
