When I was a kid, I believed advertisements. In the 70's happy faced scrubbers came out and cleaned your bathtub for you in the commercial. So when my mother sent me upstairs to clean our tub, I was so excited. I sprayed the tub with the product and waited... Nothing. Soon Mom came up and asked what I was doing staring at the tub and to get busy. It was a good lesson, but heartbreaking. You should add a section about advertisements.
