The Long Weekend

My mother-in-law decided to stay with us for an entire week. By day four she had reorganized the entire kitchen, thrown out half my snacks, and told me exactly how I should be raising the kids.
On day five I finally said, “You know, I really appreciate all your help, but I think it’s time for you to go home.”
She looked shocked. “Why? Am I bothering you?”
I smiled and answered, “Not at all. It’s just that my wife and I have this agreement — we only allow each other’s parents to stay until we start fantasizing about divorce. You’re getting dangerously close to that line.”
