Context: I'm at the coffee shop --- my wonderful, brilliant (honor society member, in fact), kind, compassionate and not to expensive house cleaner is working and I like to stay out of her way.
Every time I come to this coffee shop, I see the same dude. I think of him as Coffee Shop Dude (CSD from now on).
CSD is probably in his mid 50s with Longish gray hair and glasses. He always wears jeans and in the winter a black down coat. He uses a PC laptop and drinks Mountain Dew. He goes outside to smoke about every hour or two. When CSD speaks, everyone on our side of the coffee shop can hear him.
Once in a while he seems to tutor some other dude in physics. This has been going on for at least three semesters, if not more -- and some other dude doesn't seem to get it... or, finish the course for that matter.
When I arrived today (about 8ish AM) CSD seemed to be getting some kind of spiritual counseling. It ended when the counselor told CSD he was being manipulated -- it wasn't clear from the discussion whether the manipulator was human or the devil... but CSD went out for a smoke and the counselor packed up quickly and left before CSD came back.
So -- the big question is -- how the heck does CSD earn a living? He always seems to be at the coffee shop, and last I knew they don't pay people just to sit there and use the free internet access.
Please, entertain me with wild speculation in the comments -- today will be kind of a long day.
