This is a story as insubstantial as dryer lint and exciting as watching paint dry.
That's because it is literally a story about dryer lint and drying paint — but the ending answers a question everyone has had.
For reasons we needn't recount, my wife was spray-painting an object in the basement laundry room and noticed that the paint rose in a crimson mist. It needed prompt removal lest the room look like a New Orleans brothel parlor.
Once she started cleaning, she got to cleaning everything. You know how that goes. "Oh, the oven burner control knobs have a smear of grease." Six hours later, you're cleaning the exhaust vent with a wire brush and caustic lye.
Some people save themselves a lot of bother by never moving past the first step — knob, wiped, done, move along — and they live in happy ignorance of the amount of exhaled fats on the hood for the stove exhaust. It would never occur to them to care about such a thing, any more than they would make a weekend checklist that said "vacuum behind the fridge" or "oil hinges on attic door."
Now that I think about it, when was the last time I oiled the attic hinges?
Anyway. She cleaned the laundry room, which gleamed. But she also found some lint in the cupboard where the duct met the wall. I say this knowing the scorn it will bring from those of you who have never had loose lint.
Wife: "When was the last time we had the dryer lint duct cleaned?"
