The Sonnets LVII - Being your slave what should I do but tend

Being your slave what should I do but tend,
Upon the hours, and times of your desire?
I have no precious time at all to spend;
Nor services to do, till you require.
Nor dare I chide the world-without-end hour,
Whilst I, my sovereign, watch the clock for you,
Nor think the bitterness of absence sour,
When you have bid your servant once adieu;
Nor dare I question with my jealous thought
Where you may be, or your affairs suppose,
But, like a sad slave, stay and think of nought
Save, where you are, how happy you make those.
So true a fool is love, that in your will,
Though you do anything, he thinks no ill.
