A few minutes later we were told to put our building back on lockdown. No one knew what was going on.
When I was a boy and I would see scary things in the news, my mother would say to me, “Look for the helpers. You will always find people who are helping.”When you have to explain these things to your children, remember to keep it simple. Answer their questions, but don't go deeper than they're ready to go. Find out what they already know and help them to understand it in ways that mean something to them. Try to keep the news off when kids are in earshot and monitor their screen time online. It's okay to share your feelings, but try to reassure their safety and list some positives, like Mr. Rodger's mother did.
