“I wisht I could put you in a cage with about a million mice an’ let you have fun.” His anger left him suddenly. He looked across the fire at Lennie’s anguished face, and then he looked ashamedly at the flames.

– John Steinbeck

Of Mice and Men, Chapter 1. George threatens to lock Lennie up inside a cage. George often gets angry with Lennie because the physically very strong Lennie cannot control himself. But his anger always fades when he realizes Lennie is handicapped and his compassion for Lennie overtakes him.
