Pretend I'm naïve (better yet don't pretend): can't you set some boundaries? If you need to get out of the house why not go for a walk? Is it because doing something for/by yourself is seen as selfish (even by yourself), while before the commute was imposed by your job, so you could enjoy that alone time guilt-free?
It's really not about boundaries. It's about efficiency. If I'm at home, there's always something I can be doing more "valuable" than podcasts. Working, playing with the kids, helping with chores, etc.
When I'm driving, there's nothing I can do otherwise, other than audio. Which means either podcasts or phone calls with family or friends.
I've been WFH for about 5 years now and also have two young ones so I know the feeling :)
I've found that any chore time is now also podcast time. So things like cleaning, laundry, or mowing the lawn I've always got one headphone in (the other ear is for listening for the kids)
Yeah when I'm doing yard work my headphones do double duty for listening to podcasts and being earplugs. But that was true even before I stopped driving anywhere.
