You probably feel like there are things that would go smoother if the members of your family would just listen and retain. No one likes to hear themselves constantly repeating things like a parrot only to have the sentiment go unheeded.
After spending the evening on my knees scrubbing a particularly grimy bathroom floor near our back door, it occurred to me that if people were not wearing shoes in there I wouldn’t have to do it again so soon. So I printed a cute door hanger on my printer and cut a circular hole and hung it on the knob. It said simply: No Shoes Please. And then a funny thing happened. Everyone took their shoes off. Even the guests. Even the repair man. And all the floors of the house stayed a little cleaner.
You have knobs all over your house that are just waiting to display a “suggestion.” A closet door could say “Hang it up, Please!” The pantry could say “No snacks before dinner.” For the laundry room: “Fold it and take it.” And maybe a second, “Just sayin’.”
You get the idea.
