The Red Pony
"Maybe I'll leave Gabilan in the corral when I go to school today."
"Be good for him to be out in the sun," Billy assured him. […]
"If the rain comes, though—" Jody suggested.
"Not likely to rain today. She's rained herself out." Billy pulled up his sleeves and snapped his arm bands. "If it comes on to rain—why a little rain don't hurt a horse."
"Well if it does come to rain, you put him in, will you, Billy? I'm scared he might get cold so I couldn't ride him when the time comes."
"Oh sure! I'll watch out for him if we get back in time. But it won't rain today."
And so Jody, when he went to school, left Gabilan standing out in the corral. (1.94-1.95, 1.96-1.100)
Jody's father walked into the barn and stood with them in front of the stall. At length he turned to the boy. "Hadn't you better come with me? I'm going to drive down the hill." Jody shook his head. "You better come on, out of this," his father insisted.
Billy turned on him angrily. "Let him alone. It's his pony, isn't it?" (1.172-1.173)
Billy Buck broke in. "They got a right to rest after they worked all their life. Maybe they just like to walk around." (2.104)
