Oh the word that a lot of parents tend to despise " why", "why", "why". This shows natural curiosity.
I think that this innate trait is stifled when the adults constantly belittle the children and have no interest in nurturing this great quality. In the end boredom and a sort of sad acceptance and cynicism sets in.
Just like a trader has to always be on guard about their way of living I think we should do the same with our attitude towards children.
