Sonnet No 57: 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 any thing) he thinks no ill.
