In "At the Reunion Buffet," Alexander McCall Smith reflects on the transient nature of life and material possessions. The quote emphasizes that regardless of our attachments or perceived rights, everything we possess is ultimately temporary. It serves as a reminder that our time on Earth is limited, and we are mere guests in a world that isn’t truly ours.

This perspective encourages readers to cherish their experiences and relationships rather than clinging too tightly to objects or status. Recognizing ourselves as 'tenants,' rather than owners, can foster humility and a deeper appreciation for life's fleeting moments, urging us to find joy in the present rather than in the accumulation of things.
