I've never been drunk. I've never been high. It's not as if I never had the opportunity. I grew up in an era when uncles and older cousins would sneak sips of beer to the kids during family cook-outs. New friends in a new school offered me weed a week into seventh grade. Later that year, we had to walk one of those same friends up and down a ditch when he took too many pills one day. During my junior and senior years of high school I spent almost every weekend in neighboring Juarez, where the legal drinking age was 18. College was dotted with various parties in parent-free homes, apartments, and rented hotel rooms. And so on.
