Sonnet 57 

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