How good is Lennie's memory? Give 2 examples

Example One:

Lennie looked timidly over to him. "George?"

"Yeah, what ya want?"

"Where we goin', George?"

The little man jerked down the brim of his hat and scowled over at Lennie. "So you forgot that awready, did you? I gotta tell you again, do I? , you're a crazy bastard!"

"I forgot," Lennie said softly. "I tried not to forget. Honest to God I did, George."

Example Two:

"Oh, sure, George. I remember that now." His hands went quickly into his side coat pockets. He said gently, "George... I ain't got mine. I musta lost it." He looked down at the ground in despair.

"You never had none, you crazy bastard. I got both of 'em here. Think I'd let you carry your own work card?"
