Also going to call BS.
My first job in manufacturing was a 4.5 day week. We were out by noon on Friday. So. Much. Win! I would do the laundry and grocery shopping on Friday afternoon (the only key is that I was living in student housing, as was a coworker with 2 kids, and I had to get to the laundromat before he took up all the washers!)
Weekends were FREEEEE. Well, hubby and I cleaned on Sat mornings.
After that job, weekends became about chores. Then enter the kids. Even more chores.
I have to say, that this winter, I've missed a lot of work due to illness. Kids are barfing all winter. Anyway, even just days like today, when I was unexpectedly off a half day, were a gift! In those 4 hours, I did some PTA stuff, built two legos with my toddler, made and ate our lunch, cleaned up a bit, did an hour of work from home. (Of course in today's case, my kid wasn't the sick one, daycare was closed due to illness.) And holidays (that are school/ daycare holidays not work holidays) - my spouse and I split the days. I actually get to cook on those days. Maybe nothing amazing, but certainly more than reheating what I made 3 days ago.
GLORIOUS. Very very occasionally I've had a day off with no kids. I go to the gym and/ or walk, cook something really nice, do some quilting or crocheting, so some serious organizing, actually think about or write a blog post, read my book, take a nap - all those things that happen oh so rarely.
