Maus II reactions

An interesting question that I had was how Art's father was shaped by his experiences at Auschwitz. To me I feel that because he was given so little (clothes, food, water etc.) Art's father became frugal and thankful for the things he had later in life. I also get the feeling that he is on edge all the time and maybe that is because of the atrocities that he experienced. I think Art doesn't understand at the beginning of the book why his father wants him to be around for so long, but I think it is because his father has lost so many people close to him and wants to spend all the time with his loved ones that he can.
