The pearl by john steinbeck?

you might also mention that it is a good leson to listen to advice from others. if he would have listened to his wife and thrown it back into the ocean they would have been a lot better off and coyotito would not have died. or it could be to not listen to your greed because if he would have just sold it instead of trying to go to another town to get a higher price coyotito wouldn't have died.
