"I ain’t a-gonna do it," Wilson said. "I’ll git mean if you try."
Ma took the two bills from Pa’s hand. She folded them neatly and put them on the ground and placed the pork pan over them. "That’s where they’ll be," she said. "If you don’ get ’em, somebody else will."
– John Steinbeck
The Grapes of Wrath, Chapter 18. Before the Joads continue their journey and leave the Wilsons behind, the Joads generously offer them two dollar bills from their small savings and some pork and potatoes. Ivy Wilson refuses a number of times. But Ma Joad places the gift outside the Wilsons’ tent and the Joads depart.
