He was helping? That course is taught by a cat...
LOL! He was supposed to turn the water supply on. (It had been turned off to persuade Sally out of the shower.) Instead, he turned the gas off.
Like cats, my family members do not like to admit an incapacity. It would never have crossed his mind, when I said, “Turn the water back on in about ten minutes,” to say, “How do I do that?”
