A lot of effort to prove your wife wrong
There doesn’t appear to be anything wrong with this picture. Sure, this home could do with some better cable management, and that carpet is far too small. Oh wait, look at the floor tiles. Are those darker tiles dirty?
Yes, they were. When the husband asked his wife whether he needed to mop, she said, “Nah, they’re clean. Don’t worry about it.” But yeah, they were dirty, and he did worry. To prove his point, he mopped every other tile to create a checkerboard pattern. He then got the green light to mop the entire floor. Sorry, fella, but we think your wife pulled a sneaky on ya.
