The fact that talking to your daughter about her day when she comes home is a nuisance to you, which the office saves you from, is a very interesting detail
Where did I say it was a nuisance? I said it was a distraction. I love talking to my daughter after school, but that doesn't change the fact that my daughter coming home from school also effectively marks the end of that days 'flow'.
The parent poster said "distraction", not "nuisance", in the context of being able to be in the "flow" of programming.
