I need a tutor

So, I was riding a train with my boys. Brock was rummaging through my bag and finds my wallet. He looked through it briefly and put it away. He looks at me a few miles later and asks me if he can ask a question. "Of course", was my reply. "Did you fail sex?" I just about fell off the seat. Of course a million thoughts go racing through my head. "what?, where did you hear that?" Then I realized what just happened. I started laughing and said, "were you looking at my drivers licence?" He said, "yes". Holding back the laughter, I told him, it wasn't a grade I received, it was my gender. I then had tears jumping from my eyes and just about pee'd my pants because I was laughing so hard. Boys make everything an adventure.
