1. Scout provides an introduction to the sleepy southern town of Maycomb, Alabama in the 1930s. She describes the hot weather, old fashioned values, and poverty of the town.
2. Atticus gives Scout the important advice that you cannot understand someone until you consider things from their perspective.
3. Atticus explains that mockingbirds are innocent creatures that only make music for others to enjoy, so killing them would be a sin, like destroying innocent people. This introduces the novel's key metaphor.
