Kindness is truly a science of the utmost highest. We see it not only in humans, but we also see it in animals. In recent years, we've seen kindness being a subject of discussion and research in schools. It is better known as social emotional learning. There have been debates over the years on whether or not this type of emotional intelligence can be taught. You see kids being bullied at school and then see other kids standing up for them. Research shows that we develop empathy and emotional awareness at a young age. Take a look at this heart-felt story of a man who lost his wife. The kindness of strangers is overwhelming. This man's love for his wife is moving.
