No, it isn’t. I’ve been living it with my daughter and she is just in 7th grade now. You need to have faith and understand that the odds are worse that she would be killed or injured riding in a car with me than going to school.
It’s easy to get overwhelmed by the news of stuff like this, but you need to put it all into perspective. Life is risky and there isn’t anything you can do about it. Just teach them the skills they need and pray for the rest.
