When I was that age, and I left for school each morning, my mom was pretty safe in the assumption that the worst episode of fear or panic that I was likely going to experience that day would be caused by a pop quiz or something.
The kind of conversations that parents have to have with their kids today involves things that no parent should have to concern themselves with. Thankfully, I never had a "this is what you should do Al if a shooter appears at school" lecture.
When I was a kid, I used to roll my eyes at the adults who went on about the "good old days". Now I really understand it.
