Home is home wherever you grow up generally speaking. Unless you're one of those people who always wants to get out of a small town and do something bigger with your life, which I always did but I always wanted to come back, so home is home and its a great place for me to come back and escape the hustle and bustle of the life that I live.
I look for the moment(s) in the story where the writer risked abandoning the glory of the self in favor of the possible relationship with an other. I don't ever let the market tell me what a memoir is. The first best memoir I ever read was Leaves of Grass by Walt Whitman.
