In the novel Of Mice and Men, Lennie and George settle down close to the Salinas River before they head to the new ranch they are to work at.
George tells Lennie that they are going to have a supper of beans. Immediately, Lennie states
"I like beans with ketchup."
George tells Lennie that they do not have any ketchup. Because of the fight over the mouse, and the lack of ketchup, Lennie becomes somewhat distraught. Lennie threatens George with running off and letting George go on without him.
George, finally realizing Lennie's despair, tells Lennie that he wants him to stay. Lennie goes on to tell George that if they had ketchup, he would not eat any of it. Lennie tells George that he would "not touch any of it" and leave it for George to cover his own beans with.
