“I was only foolin’, George. I don’t want no ketchup. I wouldn’t eat no ketchup if it was right here beside me.”
“If it was here, you could have some.”
“But I wouldn’t eat none, George. I’d leave it all for you. You could cover your beans with it and I wouldn’t touch none of it.”

– John Steinbeck

Of Mice and Men, Chapter 1, Lennie and George. We see here the kind and considerate side to Lennie and he shows appreciation of his friend George.
