«So are you to my thoughts as food to life,
Or as sweet-season’d showers are to the ground».
The poet is torn by contrary feelings that he cannot reconcile. His relationship with the youth alternates between pleasure — “Sometime all full with feasting on your sight” — and uneasiness — “And by and by clean starved for a look.”
So are you to my thoughts as food to life,
Nor does he know whether to be alone with his love or show it off to the world. Embedded in these words lurks a sense of dependence: “So are you to my thoughts as food to life, / Or as sweet-seasoned showers are to the ground.” Following as it does the morbid sonnets dealing with death, in this sonnet the poet gains no pleasure either from fulfillment or desire: “Possessing or pursuing no delight / Save what is had or must from you be took.”
