how do you think art and his father's relationship change throughout book 1 and 2?

As Art begins to draw this story about Vladek's Holocaust experiences, he begins to visit his father more and more frequently. Their relationship is strained, as Vladek's gruff demeanor and unwillingness to spend money routinely infuriate his son. Art is filled with complex feelings towards his father ranging from admiration for his survival in Auschwitz, to frustration towards his aggravating tendencies, and guilt for his own neglect of a father who has lived through so many difficult times.

Art also has complex emotions towards the Holocaust. Though he did not live through it personally, he feels that he is constantly affected by it. His father's personality was largely formed from his experiences in Auschwitz, and this personality in turn directly affected the way in which Art was raised. Art is consumed by varied feelings of guilt, especially regarding the fact that his life has been so much easier than his parents'. He sometimes wishes that he had been in Auschwitz, so that he would know what they went through. Art's guilt over his father's life is still apparent after the end of the novel.
