When I wrote the previous post, I couldn't remember who said "An armed society is a polite society".

The Google thing has a real future -- it told me right away that it was Robert Heinlein.

That made me remember one of the most beautiful quotes in the world:

"Love" is that condition in which the happiness of another person is essential to your own.

This is from Stranger in a Strange Land -- which if you have never read -- run to the nearest library/bookstore and get it.
