Lennie
Large and friendly with a mental disability
"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."
These quotes show that Lennie was harmless and he didn't mean to do anything bad. He was very friendly and didn't mean to harm anyone.
