I like your definition.
I wish I lived in a world where people had that kind of class...
Well. Maybe. Really I guess I don't care (maybe this is a cop out).
There's no higher meaning to me.
Sometimes it appears that a lot people have veered away from the concepts of what could be called class as I previously defined it. Some of this is probably due to their age. One hopes that as most people mature, they will develop somewhat classier behaviors.
As I see it, when we reward bad behavior we also encourage it. There are people who make a lifestyle and often a living from what should be unacceptable actions. This is a shame. I would name names or offer examples, but recently discovered that it is not classy to do that.
