Who was Smitty in "Of Mice and Men"?Because I don't know who he was.

Smitty was the skinner who got in the fight with Crooks, the "Stable Buck," at the Christmas party. He doesn't play a major part in the book. He mainly shows up when George and Lennie are listening to stories about what the ranch and boss are like at the beginning of the book, before they've met most of the men who work the ranch and are just settling in.
