O, that you were yourself! But, love, you are (Sonnet 13)

O, that you were yourself! But, love, you are
No longer yours than you yourself here live:
Against this coming end you should prepare,
And your sweet semblance to some other give.
So should that beauty which you hold in lease
Find no determination; then you were
Yourself again after yourself’s decrease,
When your sweet issue your sweet form should bear.
Who lets so fair a house fall to decay,
Which husbandry in honour might uphold
Against the stormy gusts of winter’s day
And barren rage of death’s eternal cold?
    O, none but unthrifts! Dear m love, you know
    You had a father: let your son say so.
