Grown up or grown old?

 Like for example, what if I flay madly on the ground, cry like a mad thing in front of, say an Apple store for an ipad, will it evoke the same reactions (from passersby and parents alike) as it would have if I was a five year old? I know its not appropriate to do so too.But why? Why set different standards of behaviour for different age groups? Why do parents give in to the demands of their children when they are small and can cry their eyes out, but not when the same children grow up and discuss their wants in a matured way? Of course it has never happened to me on a larger scale and am not generalising anything here, but, I was just wondering (empty mind, devil's workshop thingy here ;) hehehe). Anyway what I want to say here is that we always grow old, but when and how do we grow up? By seeing reason in everything? By making people see reason? umm... wait! By not throwing tantrums and by discussing the matters that matter? How come do parents get to play the same roles? Why is it that we have to don different roles? Why do the children have to be someone with their parents, someone else with their friends and someone completely different with strangers? With age people stop looking at the world with wonder and start looking at with cynicism. they stop looking at nature with awe and start looking at man with distrust. The enmity between countries or between people is always actually the "wise" adults. Children fight with each other, but the next they will search the same kids and play with them together. A child is least bothered with which country he belongs to, from which section the society he is from, then why does the same child start differentiating among these things when he becomes a "matured and responsible" adult? Even great men were children once. Did they, at that stage of their lives, dream of creating fractured countries, broken ties, bitter enmities, cold war, venge-filled rivalry? If they have, then there is seriously wrong with the roots of the society. Where does the innocence go away from a child as he becomes older? One cant always blame the media. grown-ups have always more or less behaved the same over years if we look at the larger picture. We appreciate people who are 'children at heart' or ''who have kept their childlike curiosity alive". But have they actually succeded in doing so? Why is it so hard to be the person you were born as in the first place? Why try to be someone you are not? Of course adaptation is the way of survival foe human life, but at the cost of what? Integrity? Respectability? Peace of mind? Millions of journals, commercial ads, books are coming out everyday teaching the joys of living, the art of living, or even how to enjoy life and live life to the core. Why do these things have to come up? Isnt living a life. one's own life, as normal as breathing? I havnt seen any child being taught how to live life to the fullest. Then why have we, after growing older, forgotten about it? Living a life cant be the same for everyone. The harder we think about life, the harder it becomes living it. So dont just grow old, grow up. Be the child you always were, the child who always wanted to grow big and tall, but remain the same nonetheless. You can never be as young as you think you are, but you can always be the child you once were, not by crying wildly for an ipad, but by having your own sense of justice,fair and uncomplicated, a life where everything is seen in a new perspective, where we do not judge anyone by his country or race, but by the fact that does the other person play fair? Just because I didnt know how to play tag, doesnt mean that my friend didnt teach me. I have never seen communalism among children, have you?
