Why is common courtesy uncommon, when everyone agrees it is a good thing?
Courtesy is taught or not taught by parents. In my generate which dates back
before the "post war derelict darlings" arrived, courtesy, at least in the south, was taught by the parents. If the parent didn't correct for the problem the school or other parent stepped up. This was before you got arrested or sued for taking control of a derelict kid. Parents today are to busy with work or social life to be troubled with doing anything even socially with their offspring. Parents today depend on the computer, video game or mall to raise their kids. IMO

Why do they call the "funny Bone" the Funny Bone". It's not funny when you
hit it
