In the recent months I have been around kids for more consecutive hours than at any other time in my life, including my childhood. I have come to realize that there were probably many times when I was a kid that the adults around me were fed up and disgusted, but kept it to themselves because I was a kid.
The only reason you feel at ease around people at all is because you don’t really stop to think about how you might come across to them. You have grown out of your self-consciousness if indeed you ever had any. Your childhood was before you were aware of the concept, were aware even of who you were and the fact that there was indeed a right way for you to act and a wrong way.
People judge. All people do. They use their opinions of you to escape from the circumstances of their lives. They assess you in order to find a flaw so that they can feel that they are superior to you, or at least not your inferior. Only the man in trouble does not judge, becoming so swallowed up in his circumstances that he does not care about anything beyond himself.
The criteria varies based on how much of life you have seen. The "amount" of life is not measured in quantity of years but breadth of experience, how much of the range of possible human events have you seen? You grow up in a small-town all your references are limited to that small town. You cannot conceive of life on the outside, but you don’t know it, you don’t know how limited your imagination is.
