What is the world coming to? you ask when you hear such a story. And then if you are a suspicious-minded old guy like me, you think: I wonder if we are hearing the whole story? I mean, stranger-to-stranger acid splashings are pretty rare, aren't they?
Alas, our sympathy is muted somewhat when the truth comes out: It didn't happen. The woman -- obviously disturbed mentally -- did it to herself.
And I'm still wondering about the arrow-in-the-back thing, too, even though it appears to have been an accident.
