Re: Bad manners
One of the things I have grown to appreciate the importance of is some shared sense of manners. As a kid I thought worrying about which fork was used for salad was silly. Actually I still think that is silly but I didn't appreciate the annoyances caused by people that just don't care about how there selfishness impacts others when I was a kid.
Now I understand how a shared sense of common courtesy is important - to hold back people from being overly selfish (how about the idiots that insist on yelling into their cell phones in libraries, or when they are being waited on in a store, or wherever else they happen to be doing, for example).
And if I must comply with a few rules I find silly so I can exist in a society where others have a shared sense of unacceptable behavior that is ok with me. I now appreciate the idea of acceptable codes of conduct that people are encouraged to follow. I really didn't understand how selfish so many people would be without rules telling them not to interrupt others, or eating with their mouth open, or treating others with respect, or realizing you must share with others (toys, when you are a kid or time with other speakers...).
I tend to be a bit cantankerous, refusing to accept things just because that is the way things are. But I have grown to appreciate the wisdom of good manners. Within that acceptance there is still room for me (and those like me) to quibble with some of the rules of good manners, but the concept I now appreciate.
