While we’re all at home, we each retreat to our own rooms during working or school hours. (Quick aside: Boy am I thankful that we bought a four-bedroom house, giving me and Ian each our own private offices.) Of course we close the door when we need to be left alone. But it’s hard to tell what the closed door means. Is the person in a meeting that can’t be interrupted? Does he just need to focus, but a quick question would be okay? Benji in particular has a hard time not coming in talking, and I’ve had at least a few times of slightly embarrassing un-muted incidents where colleagues have been treated to family conversations.
