Well yeah. I think you're the one missing the semantics here.
Part of the point was that Charles was working for quite a bit longer than his supervisor thinks he did. Besides the space invaders (Which was poor form, and something I would never dream of doing on an hourly wage.) he was in fact planning out the program. (See the time spent scribbling notes.) It just didn't look like it because he wasn't creating a huge fanfare surrounding the process. Alan jumped right in with some hazy OOP sketches and sort of "hacked it out by committee." as he went along.
He's lazy because he thought about the problem instead of doing the "straightforward" OOP, headache inducing four module style design favored by Alan.
