Contrast: On page 131, the father is walking through town with his son holding one hand and his revolver in his other hand. I thought that this was an important contrast because you have the thing keeping him alive (son) as well as what could kill him (revolver). In the section before, the fathers thinks about killing his child and now he has the weapon and target in either hand.
How long have they been in a post apocylptoc world if they are still able to smell cows.
Why does the father always leave his son while he searches around? Wouldn't you be nervous that your son can be taken while you are not their?
