LOL. More likely the snarled “WHAT?!?!” when he interrupts my deep thought. He’s learned, though. He starts by asking, “Do you have a minute?” I can answer “No” without breaking concentration. If I don’t answer at all, he knows I’m REALLY concentrating. (He used to stand in the doorway of my office until I noticed him — that doesn’t work now that he’s sharing office space.) He’s often very confused when half an hour or an hour later I ask, “So, what did you want to talk to me about?” He can’t remember what seemed so very urgent at the time… :-)
