Wondering about life is one weird exercise. There are some strange twisting points in there, when things reveal themselves in queer manners. It's hard to explain but, for instance, there are certain moments when I notice that there these things that we assume we know about life are so far how others tell them to be. But them we get on the battlefield, and we see several more stuff we can't understand how no one ever told us about.
One of these things I'm learning by myself is about how life tries to push us away from ourselves. And it's made so by some complex conditioning combinations that lead us to close our tolerance towards some stuff and locking ourselves from others, all because by several reasons we can feel threatened by the world around us.
What I am trying to say is that apparently innocence can leave us wiser in reasoning. By scarring ourselves through life, we get so easily biased by all associations we make towards things that we become grumpy old fellas, with rancorous assumptions and being obnoxiously opnionated.
We can't, however, remain innocent through life, for we won't meet life. But we can't let ourselves be scarred by everything, and let wounds to get deep enough to damage our natural opinions about some matter to be stained by an external agent, and start hating a group of people for the sake of one person, or generalize a whole genre of experiences due to one bad experience. We can't let our judgement on the world suffer such detours.
