We find every child a cute child. We enjoy looking at the children, love playing with them and share their happiness and innocence with joy. Why? Is it only because the child is a lovely child in looks? That is not true. We mainly enjoy being with children and love them because they are honest. We love children because of their innocence. We love children because we are sure that child will not judge us and that we can be totally free with the children without any fear.
Let us examine our relationship with grown ups. With most of our friends and acquaintances, we are guarded in our approach. We think before speaking. We try to hide most of our true feelings and try to act in a way that we believe will maintain a make believe relationship. How many times, have you thought of shouting at someone, but have refrained from doing so? How many times have you wished to laugh at someone's dressing sense but have stopped that laughter? How many times have you really wanted to tell someone few things but stopped midway worried that it may spoil the relationship? Please think about the artificial way in which we relate with grown up people. We do all this because we are unsure of ourselves. We are unsure about the other person's reaction and intelligence and we are unsure about the relationship.
With a child nothing of this kind exists. We are free to express ourselves in as many ways as we wish, without any reservations. That is why we love children and call them cute.
