Glasses of our fathers

I assume part of growing up is to throw away our childhood glasses and look at the world around us with our naked eyes. Depending on morals and attitudes of our family and the place and time we grew up in we have different brands and model of glasses on. Religion and politics play an important role for sure but at the end it all goes back to family and how they see the world. When trying to explain the world around us for kids we always have to decide on how much of the truth can be told. How people treat each other in real is considered too much for a little one's world.
Well I have certain doubts about this behavior of human race. For instance think about any of those things we hide from kids and assume it was something that could be seen on streets every day. It was not a secret any more and all kids would know about it from the beginning. Would it still be problematic?
For now every family has to use this protection glasses. The problems raise when we forget to change these glasses in time as the kid grows up. Many times when the kid is not a kid anymore and leave the house to start its own life these glasses are still there. Family is not around anymore and sooner or later these glasses break into pieces and reality comes in but in a shocking way.
I guess some people decide to learn about the real world at this time. They need to spend a lot of their productive years on exploring things that they should have done years before. They would always feel this contradiction between their childish needs and their responsibilities in the society as an adult. When they can overcome the problem depends on many things. Some people never escape from this frustration.
In reaction to the shocking reality some people though glue together all the pieces of the glasses and  put them back. The shock is so huge that they cannot bear it. They decide not to look at those things that bother them or even deny their existence. They will be vulnerable people that the shock can attack them every now and then. They are in a constant escape from reality and remain in their childish world. This can have a much more devastating outcome comparing to the first group. Those people at least now there is a problem and are in a constant struggle to tune their childish behaviors to their responsibilities as adults. The second group don't see the problem. They act childish when they need to be an adult and it can happen in their social or personal life. If they are lucky some day they understand it and join the first group but they are way behind in their life.
