Since the line in the poem is not mention, and even the poem itself, here's a quick answer about the usage of metaphor and simile.
<span> In general sense, metaphor has a stronger assertion compared to simile . A metaphor implies that A "is" B ; a simile only says that A "is LIKE" B.</span>
D. An individual who serves as an example of positive behavior.
He has children in three grades: second, fourth, and sixth.
Based on this line from "My Father's Sadness", the line <span> “his young body is dying of responsibility" means that, the speaker is aware that she understands that her father is dying, and that the burden or responsibilities of life is slowly taking away his young body, having a slow and painful death. Hope this answer helps.</span>
