2. Lennie and George both want their own farm to gain freedom.
3. Candy made an accurate yet hard decision to put down his dog.
4. Candy loved his dog and submitted to peer pressurewhen he allowed him to be killed by Carlson.
5. George lies to the Boss about Lennie being his cousin in order to keep Lennie on the farm.
6. George and Lennie's friendship has allowed George to learn trust, and he shares personal details with Slim.
