unknown

i have been bombarded by this 'uknown' fellow that's been showing up in my work the
last few days.  he's troubling to me because he doesn't have a number and when i've been
introduced to him, it is always as 'unknown.'  he feels ?spectral? but i am changing my perceptions on him with every painting moment. no one else seems to be bothered by him--as usual--which is irritating to me, because the very uncertainty of him makes me nuts...which is irritating because i thought i had a handle on this.
