   Note: ``In Old English, generally, thou is the language of a
         lord to a servant, of an equal to an equal, and
         expresses also companionship, love, permission,
         defiance, scorn, threatening: whilst ye is the language
         of a servant to a lord, and of compliment, and further
         expresses honor, submission, or entreaty.'' --Skeat.

   Note: Thou is now sometimes used by the Friends, or Quakers,
         in familiar discourse, though most of them corruptly
         say thee instead of thou.
