Both of them were determined to follow their goals. Jeffery and Harris
suffered and ha consequences. Jeffery suffered because he was sold to a new owner and his love was still waiting to be sold. Then Jeffery begged his new master to buy his love. Then he face the consequences when his master went to buy his love. When he went he saw his love and she was being sold, but with a family and his master did not buy her. Harris suffered by the farmer who had told them to stay in his barn and the farmer betray them by telling someone where they were hiding. The consequences were the he was beaten and put in a jail house in the town he was staying at.
Rather than having similarities they both have differences. One of the differences that they have is Jeffery failed to accomplish his goal. Then Harris succeeded to accomplish his goal. Jeffery was sold to a new master and Harris was a runaway slave. Then Jeffery was hurt emotionally because he was not with his love. Harris was hurt physically because he was betrayed and got caught. Jeffery gave up because he was alone. Then Harris did not give up and he went on to be a free man. The last thing that makes them different is that Harris is fearless and regardless of any laws. Jeffery is fearful and followed the laws.
Therefore, Jeffery and Harris have all of things in common. Even their difference from each other. Jeffery gave up and never saw his love again. Then Harris never gave up and accomplish his goal to be a free man. They were both slaves who want to accomplish their goals.
