from what i see you didnt really read the poem as a whole but rather on each line without connecting the meaning to each one of the verse, and thats fine!
here some explication in case you were lost>
Carry your griefs like a father, Steady like a solider, mother,
usually, fathers are the ones who go to war and are soliders and mothers are the ones who bear their loss so i reversed the roles for a surprizing effect cuz it is not in the litteral sense it is methaphoric, so like father s grief, in silent, mothers also fight like soliders, meaning like fathers, and this is tied as a summary to the first part which goes: All those who speak were once a soul >All those who cry were once a child It is about childhood and that we all had the similar fears and darkness and eventually grew over them
and the ending is a plea that will never be listen bcs empty words, they will reach no one bcs there is no plea to begin with, the ending is a trap. and now tie this to the mid section with mother and father.
