This quote from Harper Lee’s Pulitzer Prize-winning novel, set in the US state of Alabama in 1936, highlights a number of changes observed in the developed world post-World War II (WWII). In this brief passage, we read of children running unaccompanied in the street, a parent (Atticus) walking home from work, and the presence of local destinations (the post office) proximate to homes. In a few words, the quote underscores changes observed in the way we work, live, shop and commute, and speaks to the restrictions placed on children’s independent mobility in the twenty-first century.
