I might have skipped this comment too, because all I'm doing is essentially nodding.

It's true that there is always change. And I don't cotton on to the "the more things change, the more they stay the same" school of thought. But it is also true that there are a few principles [1] that have always been and probably always will be applicable.

[1] Used for lack of a better word; I don't consider some people who have certain principles "principled" people at all. Don't you just love English?
