Our son will be 12 next month and for the most part, except for his premature beginnings, his life has been relatively stress free. As parents, we try to keep it that way, but we also feel it is our job to tell him about the world. We've always shared news at age appropriate levels. He's known about September 11 since very early on, especially since his birthday is close to that date, but in general terms. His school has been great; talking about tragedy with increasing detail as his maturity grew. However, we have been at a loss how to explain the happenings in Ferguson, Missouri, this week. Yes, we told him what happened to Trayvon Martin. Yes, the legal system failed Trayvon as much as the vindictive racism of George Zimmerman. But in Ferguson, there are so many things I can't even believe, how do I explain it to my kid?
