You reminded me of a sad video that I wish I would never have seen a few years ago. It was captured by traffic cams. It first shows a dog who was hit on a freeway. Another dog braved four lanes of fast moving traffic, grabbed his injured friend by the scruff, and drug his injured body all four lanes to safety. I cried. Then it showed footage of a child who was hit on a road. People kept right on going. I cried harder.
