Final answer:
Klipspringer calls after Gatsby's death only to ask for his tennis shoes, showing his self-centered nature.
Step-by-step explanation:
The only reason Klipspringer calls after Gatsby dies is to inquire about a pair of tennis shoes he had left at Gatsby's mansion. He does not call to offer condolences or to inquire about the funeral arrangements, which reflects his opportunistic nature and highlights the theme of the superficiality of some of the characters within F. Scott Fitzgerald's novel, 'The Great Gatsby'. Rather than mourning the loss of Jay Gatsby or showing concern for his demise, Klipspringer is solely focused on retrieving his personal belongings, demonstrating his self-centered character.
