“Then Pa looked straight at Laura and said, 'You girls keep away from the camp. When you go walking. don't go near where the men are working, and you be sure you're back here before they come in for the night. There's all kinds of rough men working on the grade and using rough language, and the less you see and hear of them the better. Now remember, Laura. And you too, Carrie.' Pa's face was very serious.
'Yes, Pa' Laura promised, and Carrie almost whispered , 'Yes, Pa.' Carrie's eyes were large and frightened. She did not want to hear rough language, whatever rough language might be. Laura would have liked to hear some, just once, but of course she must obey Pa.”
