Have you ever made the big mistake of calling your wife fat?
I mean, not directly fat but even something like "let's go exercising."
Not direct but it is just like saying you are fat.
My wife doesn't get mad that often but one time I said something indirect and she took it very hard.
Yup, sofa for me. I did kind of like sleeping on the sofa while watching TV. But the cold shoulder from her was killer. Luckily she doesn't hold a grudge, it only lasted one week. (Just kidding, one night only.)
But here is a sign for you dummies like me.
