Food for a very great deal of thought here. In the past, I once said of a woman who married an unrepentant bastard that I knew (not an abuser - that I know of, but a greedy, narcissistic, cheating sociopath), "She signed up for it." This woman knew what he was, and she married the jerk. But this link ... Well. As my oldest friend and I used to say: "It is to sigh." It's never as easy as that. And it isn't as funny as this. So read this link, please read it - and take it to the final paragraph, which is incredibly important.
Have a while to get lost in a beautiful, detailed tree-style map of the history of world languages? Sure you do! So enjoy. It's gorgeous.
