Lennie attracts many weaker characters (Candy,Curleys wife, etc) in the novel. Do you find that interesting? What connections can be made between them?
the people are Candy, Curleys wife, Croooks and others
I think that's very interesting and is one of the themes of the book-- the weak have much in common and are oppressed by the strong. In fact, you could also say that even within the world of the weaker characters, the weakest are still victimized even by those just "above" them on the social food chain.
Even in an accidental death, when Lennie kills Curley's wife, we see just how weak and fragile the position of the weaker characters is, even within the context of friendship between two outcasts.
Isn't it obvious that Lennie attracts these people bacause he is easily manipulated. He can also be trusted with information because who would believe the mentally challanged person and let's face it George doesn't let him talk to most anyone anyway.
