Answer 2

An adult's perspective on life is different from that of a child's because of the difference between their respective experiences and exposure to the world around them. An adult comes across all sorts of experiences-good or bad, pleasant or unpleasant, encouraging or discouraging,happy or sad.The child lives a sheltered life under the protection,surveillance and love of his parents. In their rosy dream world of fairies and wizards, nothing good is impossible for their favourite characters. Their adoration of these characters is nothing lot to a hero-worship.
The world of make-believe make children lovers of romance,beauty and all the pleasant things in nature. These characters are their super-feasts, which are being lucid but seems to be real in dreams and stories, but may not be in real life. The adults who are familiar with harsh realities of life know that all that glitters are not gold. Everything is not meant to be sweet as honey, there accept the things critically with a pinch of salt.
