What is he building in there?

There's this guy. He's about 50 years old and Asian. Uniform: black wool trench coat. Before I get ahead of myself, for convenience purposes, let's name the man Harry. He looks like a Harry (not Potter) but if any Asian man were to be named Harry, it'd be this guy. Harry sits in the same place at the same coffee shop everyday. How I know this if I'm not there everyday? I just do. I just do.
It's comforting when I walk the stairs to the dimly lit table in the back and see him sitting at the far left corner. He's the watchman. Harry probably won't look at you while you're getting your work done, but he'll certainly acknowledge your initial presence and will always say goodbye when leaving. I can hardly understand a fucking word he says. I don't think anyone really can. I am almost positive he's a genius.
I think I'm getting ahead of myself though...I wanted to set up a real scenery for you. Let's talk about the coffee shop. Harry's domain, if you will. This coffee shop is a place where all homework, side-work, fun-work is fully accomplished. The people here have focus and I like it. The couple in the corner have made a make-shift home office. The guy even has his shoes off for crying-out-loud and is using the decorative pillows as his laptop rest. Instead of going in-depth about decor, let's just say it looks like small house that is owned by an artist who is very conscious of lighting...are you still with me?
Harry is the ultimate observer. He sits there soaking everyone's creative energy in. The man does have a laptop. What is he writing so intently about? Let's be honest here... this is Breakfast at Tiffany's except there is no expensive jewelry and no story line that involves the concept of love. What isn't realized is that we're all being fooled. We're all part of his next great novel or crappy article on some web page that no one has heard of. Either way, we're a part of it.

Harry says, "Have a nice day" and the back of my mind chimes "Thanks for the material."
