Reason for stopping: finished the scene. Don't really feel like writing any more, and I'm hoping the next scene will crystallize nicely in my head somehow if I whistle and walk away.
Faustus: When I behold the heauens then I repent
And curse thee wicked Mephostophilis,
Because thou hast depriu'd me of those Ioyes.
Mephostophilis: 'Twas thine owne seeking Faustus, thanke thy selfe.
But think'st thou heauen is such a glorious thing?
I tell thee Faustus it is not halfe so faire
As thou, or any man that breathe on earth.
--Christopher Marlowe, Faustus, Act II scene ii
