Sometimes, I was fortunate enough to be tagging along when he would hang with his friends and talk shit. Typical, locker room talk. But afterward, he would always make sure I understood that 95% of what I heard was just that...talk. I learned at a young age that you brag & boast with your boys but you come home, kiss your wife, take the trash out and thank her for the things she does.
We also had sex ed class in 6th grade (at a Catholic school, no less). I'm still a little shocked that there are people who don't want their kids to learn about the basic biology of it.
