Rated R Movies

To make up to the family for drinking my dad would usually take the family to a double feature at the drive in, and if that night happened to be in the middle of a school week then so be it. My dad didn't care of the effects of going to bed after midnight was having on us kids, and my mom for sure wasn't about to tell my dad, no the kids need there rest. So off to the movies we went, and back then there was no rating for Mexican movies, and again our well being was not taken into consideration. So as children, and I am talking about ages of 4yrs old and up sat through movies that had sex, nudity, violence, and foul language. Not once were we ever told not to look, and the words the children should not be watching this movie lets go were NEVER mentioned. I lived in world where the kids never came first.
