Climbing my grandfather

Question 1

What is the structure of “climbing my grandfather”?

Answer 1

Repetition of the extended metaphor of “mountain”-

Ending of the poem of “good heart” - ends the poem in a positive note which reflects the relationship being good and positive

The unbroken poem (no stanzas) could reflect the solidity of his grandfather and how reliable he is. Reinforce the extended metaphor of the “mountain”
