Shakespeare's Sonnets: Look in thy glass and tell the face thou view'st

Look in thy glass and tell the face thou view'st,Now is the time that face should form an otherWhose fresh repair, if now thou not renew'st,Thou dost beguile the world, unbless some mother.For where is she so fair whose un-ear'd wombDisdains the tillage of thy husbandry?Or who is he so fond will be the tombOf his self love to stop posterity?Thou art thy mother's glass and she in theeCalls back the lovely April of her prime,So thou through windows of thine age shalt see,Despite of wrinkles, this thy golden time. But if thou live rememb'red not to be, Die single and thine image dies with thee.
