Don't know why they call it that. Selfish people. It's a double day for those of us entertaining the kids once they get out. They're not even properly exhausted or homeworked up.
Maybe chores is the solution. Come home and fold clothes, kids.
But then there's also the parent-teacher conferences. I still can't believe I'm on the parent side of this equation. Which reminds me, I still need to sign some report cards.
