Which do you think are the most poetic lines? Why?

Explanation

The last stanza of the poem seems to be the most poetic, which is: ‘It went to some forgotten place,
That’s hidden in an infant’s face, That’s all I know.’
These lines sum up beautifully the process of growth and the disappearance of a particular stage of life. These lines express metaphorically that an infant’s innocent face hides many things behind its smiles. He seeks solace in the fact that the virtues of childhood are not permanently gone but perhaps it lies hidden somewhere in the child’s consciousness.
