Rob Smalley is a parent of three who, after watching the morning news Sunday, took his kids down to D.C.’s British Embassy to lay a bouquet of flowers.

Smalley said he was there to give his condolences and to show solidarity.

Rogers also famously encouraged parents and children to look for the helpers who rush to the scene of a tragedy.

"Because where there's helpers there's hope," he said.

It's advice Smalley is taking to heart.

"I'm trying to teach them to be aware of their surroundings to make plans as to what to do if something does happen," he said. "But to continue to live your life because sheltering in your house is not the correct way of living.
