In Toni Morrison's novel "Sula," the story of two friends unfolds over a decade marked by separation and change. Their lives diverge significantly during this period, leading to profound personal growth and introspection. When they finally reunite after ten years, the meeting is not just a reconnection of friendship but is also symbolic, representing the passage of time and the evolution of their lives.

The phrase about their meeting being "thick with birds" suggests a rich and layered experience, filled with memories and emotions. The imagery of birds can signify freedom, change, and the complexity of their relationship, indicating that while they have been apart, the bonds of their friendship remain significant. Their encounter encapsulates both nostalgia and the inevitable changes that come with time.
