He liked to start sentences with okay, so. It was a habit he had picked up from the engineers. He thought it made him sound smarter, thought it made him sound like them, those code jockeys, standing by the coffee machine, talking faster than he could think, talking not so much in sentences as in data structures, dense clumps of logic with the occasional inside joke. He liked to stand near them, pretending to stir sugar into his coffee, listening in on them as if they were speaking a different language. A language of knowing something, a language of being an expert at something. A language of being something more than an hourly unit.
