The interaction between George and Hazel develop Kurt Vonnegut's social criticism by:
D. Showing how technology can dehumanize and desensitize people.
Vonnegut shows an scene in which Hazel is crying about "something real sad on television" however she can't remember exactly why she is crying. Finally, George advices her to forget about it to what she replies that she always does. In other words, technology, in this case TV, can make one feel instantaneously sad however one aims to forget it and move on. Therefore, technology is dehumanizing people by creating instantaneous moments of sadness that one quickly forgets.
