Perhaps this has happened to you: You’ve lived with carpeting, and then for one reason or another you live with hardwood or some other type of hard surface flooring that shows up every little bit of dust and dirt. You can’t believe it! You can sweep or vacuum one day and by the next morning, the dust and dirt have returned.
Of course, we think that some new dirt-and-dust-producing thing has mysteriously descended on our living space, but the truth is it’s the same dust and dirt that has always been present, only now we can see it.
