This is an example of one of the worst punishments that Dave's mother tries to inflict on him, and it makes clear just how cruel she truly is. Many times, it seems that she actually does want Dave to die, even this early on in his abuse—and it only gets worse as time goes on, when she explicitly states that she wants her son dead. This is also the moment when Dave realizes he can manipulate her and use tactics to ensure his survival.
