Has anyone read 'The Reluctant Fudementalist'(Read the Details)

I have read, discussed, and wrote about the book; however, I am having problems writing about one subject in particular. This is the question I am to respond to(question 3, Nostalgia. Home. Memory….) Now mind you I am not asking you to do the work for me, in fact I already have a page and a half written. I am just having a hard time explaining myself. I understand the question, but still need further sources rather than the book on this subject. Do you have any input on the question, or any sources that could help me better understand and explain?
