I definitely need that separation.
My wife will sometimes just let our 6 year old walk on into the shop in the middle of the day. I love him to death, but he needs to be watched like a hawk in there, but she just sits in the house. She expects me to tend to all sorts of house-related BS while I’m working. Sometimes she’ll call me all exasperated, wanting me to come in and help with our son because he won’t listen.
I’ve explained to her a million times that “I’m at work” means “I’m at work”, and I wouldn’t even think to call her to come help me manage our child while she’s at work.
On an intellectual level, she gets it. In real world practice, nope. Not at all.
