lennie touched a womans dress and did not let go because he like to touch things that are soft.
curly ame in the bunk house and saw that Lennie was laughing so he immediately thought that Lennie was laughing at him. Lennie was laughing about the rabbits that goerge and candy were talking about. Curly thought he was going to beet Lennie but Lennie ended up with a broken hand.
George kills Lennie because he thought that was the best decision. He had 3 decisions. Fist was that curly was going to kill him but was gonna make him suffer. Second he would get send to jail but was gonna get treated horrible. Third was that he had to kill him right away and he would just die instantly and not suffer.
