When forty winters shall

Time for sonnet 2.

HEN forty winters shall besiege thy brow

And dig deep trenches in thy beauty's field,

Thy youth's proud livery, so gazed on now,

Will be a tottered weed of small worth held:

Then being asked where all thy beauty lies,

Where all the treasure of thy lusty days,

To say within thine own deep-sunken eyes

Were an all-eating shame and thriftless praise.

How much more prasie deserved thy beauty's use

If thou couldst answer, 'This fair child of mine

Shall sum my count and make my old excuse,'

Proving his beauty by succession thine.

This were to be new made when thou art old

And see thy blood warm when thou feel'st cold.

Once I understood that sonnet 1 was about a guy, his vanity and the offerspring that he supposed to have, the context and the meaning of Sonnet 2 becomes more obvious. This sonnet is all about the encouragement and the question of what the youth did with his lustful ways and did he have a son to feel warm in his old age that he is being seen in the form of his son.

Hmm, it is a nice sonnet, didn't feel the rush though.
