I'm not saying I'm blocked or blocking someone, I'm saying I'm tapping out. At 4pm-something I'm not going to spend the next half hour reloading the context in my head and getting back to where I had been before the 2-minute (i.e. 15-minute) call, not because I can't, but because I'm tired and don't want to. If I were working at a hospital and debugging a medical device that somebody needed to have online that evening, then you can be darn certain I'd reload that context in my head over and over until the work was done. But for shipping widgets back and forth, there's no point in making myself tired and resentful. I can pick it up the next day.
