Yeah, I do the exact opposite, i want my life to blend (work and personal) during work. That's the advantage. I like my children climbing on me, or I like hearing what they are doing. If I need to focus, I will just focus, I don't need a separate environment. If they are particularly loud (scream continuously), I would ask them to lower their voice, that wouldn't be acceptable even if I wasn't working.

After work, I don't let it blend unless there are emergencies. if it doesn't blend while working, it would feel lonely, instead having lunch with my wife is quite nice!
