Which phrase most contributes to this passage's sad and isolated tone?
I will never forget that lonesome hill of stone that is her
final bed, as it fades from my sight. I tread softly by my
uncle, my hand in his. I walk with my head turned, watching
that small hill as it fades from my sight. The soldiers make
us continue walking. My uncle talks to me, trying to
comfort me. I walk in loneliness."
-Michael Rutledge, "Samuel's Memory
