Oh George, I am sorry i forget everything, i can leave!
No, I made a promise to your Aunt Clara, im gonna take care of you Lennie!
...and you are nice company after all.
Why should I do all the work? UNFAIR!!!
Always bored when I'm Alone!!!
Why should I work alone?
I am so scared right now!
George gets mad at Lennie for not remembering things, but they still have to stick by each other because that's all they have, alsoLennie is George's responsibility after all. Lennie lost his Aunt Clara so there is no one to look after him.
On this scene we can visualize a concept of "LONELINESS". In the book OMAM there is a part that says, Farmers used to work alone but as any human, farmers felt Lonely and they said that it was unfair, they felt scared and other reasons.
