Quotations that something is about to happen in chapter 2 from of mice and men?

In of mice and men there is a lot of foreshadowing. I forgot exactly what's in chapter two, George (I think his name was.. The sane one) says that if Lenny (mental one) does something wrong to go to the forest or the spot to hide. That is foreshadowing he will do something wrong. Also when they are traveling to the farm in the beginning of the book, Lenny kills the mice in his pocket because he is so strong. That foreshadows that his strength will cause trouble in the future. Hope this helps
