Is it for fear to wet a widow’s eye
That thou consume’st thyself in single life?
Ah, if thou issueless shalt hap to die,
The world will wail thee like a makeless wife;
The world will be thy widow and still weep
That thou no form of thee last left behind,
When every private widow well may keep,
By children’s eyes, her husband’s shape in mind.
Look what an unthrift in the world doth spend
Shifts but his place, for still the world enjoys it;
But beauty’s waste hath in the world an end,
And, kept unused the user so destroys it.
          No love toward others in that bosom sits
          That on himself such murd’rous shame commits.

By William Shakespeare
