WTF?! I know this piece is only indirectly about your invisibility, Ginger, but seriously?
If we were reading a piece written by a male mechanic whose stay-at-home wife said she was sick of seeing him come home in grease and oil stained clothes all the time, I think every reader would say, "WTF?!"
And I kinda hope every reader here says the same.
You're heroic. I would have lost my mind caring for half as many kids, cheese potatoes or no. And it sounds like you did a great job: if your son had a part-time job at a daycare, he's got some wonderful qualities.
All best, my friend.
