Which side do you use?

Do we really need quilted toilet paper? As I sit contemplating life I wonder maybe there is a reason for this. Someone somewhere must have thought two different sides was a good idea. I'm sure it cost the companies millions to re-tool their assembly lines to produce this new product. So what could be the purpose? Where would one go for answers? I don't think I'm going to call the 1-800 customer service number and asking them, maybe later. I guess it's up to me... and here's what I've figured out. The smooth side is when you just need that delicate touch. And the quilted side? That's the toilet paper equivalent to sandpaper. When you really need to scrub. Ruffles have ridges. When two hands just aren't enough.... Where's my paint scraper.
