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

The lines that seem to be the most poetic are:

‘It went to some forgotten place,

That’s hidden in an infant’s face;

That’s all I know.’

The above lines conclude the questions and the speculations of the poet regarding his lost childhood. The lines beautifully depict the poet’s realisation of the loss of the most important stage of his life. He finally realises that his childhood has gone to some forgotten place and that place could only be found hidden in an infant’s innocent face.
