Mytery Signs Near Barnes & Noble: Crazy Person, or Someone With More Hobbies and Goals Than You?

FiPS reader Edwin recenly tipped us off to the appearance of mysterious signs (posts? rants?) on an electrical box across from the Barnes & Noble on 7th Ave. It's easy to assume, at first glance, that you're looking at the diatribes of a crazy person. But that's really not fair -- there's actually a lot to be gleaned from careful examination of the signs. I have studied the images below and concluded the following about the mysterious poster:

1) They own, and are adept with, a yellow highlighter.

2) They are considering possibly returning to school to get a nursing degree.

3) They may be Park Slope's -- if not the world's -- foremost author of Dick Cheney autobiography fan fiction.

Or maybe I've got it wrong - anyone else have a theory?
