Lennie kills Curley's wife. She walks into the barn when he is there with the dead puppy, he sais he is not supposed to talk to her and that he does not want to get in trouble, but she sais that nobody is going to notice because they are playing outside, She sees the dead puppy and they start to talk, They talk about their dreams "to" eachother but not "with" eachother, Lennie sais he likes to pet nise things and she tells him to feel her hair because it is so soft, He starst stroking it and loses controll (he can't stop), she gets scared and starts screaming, Lennie grabs her and tries to make her stop because he don't wants George hear, he kills her by breaking her neck. When he realices she is dead he understands that he has done a bad thing and that he is going to get trouble so he runs away to the place where George had told him to go if he ever got in trouble.
