Answer and Explanation:
The author realizes that there are 3 situations in which children believe that they observe, experience and practice kindness and this changes according to age. According to the author, older children believe they are kind when they help, show respect, encourage or defend someone. On the other hand, younger children have an even more surprising result, as they believe it occurs when they help someone physically or emotionally and when they share what they have.
The author achieved these results by asking the children to speak when they are kind, through a short text or a drawing (in the case of younger children).
