How does the figurative language in the last three lines of the poem contribute to its overall meaning?from Davids old soul Daids Old Soul:As far back as I can remember, my

mother has called me "an old soul."

I never understood. But now that our family has

dwindled1 to just Mom and us kids, I’ve grown

into a man. You do what you have to. "David, dig deep,"

is the whisper in my ear. So I stand strong like

a tree my baby brothers can lean on. I try to be the

raft that helps carry them over this life’s rough rivers.
