In Alexander McCall Smith's "The No. 1 Ladies' Detective Agency," the narrator expresses a sentiment about how deeply rooted one's sense of home is. The idea conveyed is that despite the allure of new places, like Zululand, each individual carries an inner map representing their homeland. This personal map is shaped by experiences and emotions, making it impossible to fully erase the ties to one's origin. The quote highlights the permanence of these feelings. While one may venture to different lands and seek new adventures, the connection to one’s native place remains strong. The heart acts as a compass, always pointing back to where one truly belongs, ultimately signifying that no matter the distance traveled, the sense of home is a fundamental part of identity.
