Here Oskar is talking about elevators in skyscrapers in this quote: "Sometimes I think it would be weird if there were a skyscraper that moved up and down while its elevator stayed in place. So if you wanted to go to the ninety-fifth floor, you'd just press the 95 button and the ninety fifth floor would come to you." (3)
A year after his father's tragic death, Oskar still has trouble getting into elevators because it reminds him of his father. "Even after a year, I still had an extremely difficult time doing certain things, like taking showers, for some reason, and getting into elevators, obviously." (36)
"I took the elevator for the last time." (68) This quote shows his sadness towards the death of his father.Oskar is so scared and sad of his father's death that he won't even get into an elevator because it brings back unwanted memories.
