Back Foolish Tears

Juliet: Shall I speak ill of him that is my husband?
 Ah poor my lord, what tongue shall smooth thy name,
 When I thy three-hours wife have mangled it?
 But wherefore villain didst thou kill my cousin?
 That villain cousin would have kill'd my husband:
 Back foolish tears, back to your native spring,
 Your tributary drops belong to woe,
 Which you mistaking offer up to joy:
 My husband lives that Tybalt would have slain,
 And Tybalt's dead that would have slain my husband:
 All this is comfort, wherefore weep I then?
 Some word there was, worser than Tybalt's death
 That murder'd me, I would forget it fain,
 But Oh it presses to my memory,
 Like damned guilty deeds to sinners' minds,
 Tybalt is dead and Romeo banished:
 That banished, that one word banished,
 Hath slain ten thousand Tybalts: Tybalt's death
 Was woe enough if it had ended there:
