There are NO dumb questions!
Sounds like your doing reverse stockinette on the body of the sock if the smooth side is inside. So after you finish ribbing you are purling all the way instead of knitting all the way. The purl stitches are the bumpy ones and the knit ones are the smooth ones.
Sure you can just turn the sock inside out, it should look about the same. Though I can knit faster than purl, so if it were me I'd do it the other way just to be faster, but the end result will be about the same.
Better to learn the knit body of the sock though because once you get into following a fancy sock pattern, then the reverse might not look exactly as it's supposed to.
Does any of that make sense?!?
