Humans are kind in nature. Just watch young children. They are born with natural kindness. This is the main reason it’s so wonderful to be around children. They constantly give and engage in a way that makes you want to give in return.
Research has found that kindness is contagious. If you want to see it in action, try smiling at people as you pass them on the street. Smiling is an act of kindness! And when you smile, people smile back.
When babies see a puppet show with kind and affectionate characters, followed by rude and mean ones, they prefer the kind puppets. Yes, they were just babies. But they have an innate ability to mirror their surroundings. They can notice the tone of the voice and actions.
