Holding a Program in One's Head (2007)
I wish there was a way to send this to my programmer coworker without seeming like a jerk.  He insists we "work" together, meaning, we're in the same physical space, working on two different projects, and he interrupts my train of thought every 2 minutes with an arbitrary question about the thing he's working on.  I'm close to a snapping point and don't know how to address it tactfully.  What I want to say: "us working together may enhance your productivity by 50% but slows mine down by 80%."
