The most interesting thing about Matt is that he actually lets his dad leave him alone, I think this is a sign that Matt can survive on his own and that he wants his dad to be proud of him. He is so used to having neighbors help out and go to the market, but now he has nothing but a house and food resources.
Matt and Attean’s friendship has grown because Attean is starting to understand Matt’s world and how he lives by listening to Matt read Robinson Crusoe. Matt is also understanding Attean’s world and how he hasn’t gone into the outside world before and doesn’t think like Matt thinks. I know this because Attean always thinks for himself and doesn’t really want to learn more about Matt’s world.
