I haven't read that one, but I've heard the famous quote - "She could have been a good woman...if it had been someone there to shoot her every minute of her life." - which I'd always interpreted as meaning that we'd all be good people if we had the threat of imminent judgmental (death, hell) hanging over us at every minute.
Anyway I liked this:
The fact that there's a brevity to human connection and human empathy—the fact that it goes away—might make you feel that we should not make a big deal that it was there at all. But of course we can't do that. We have to value the moments when a person is everything we'd hope this person would be, or became briefly something even better than she normally is. We need to give those moments the credit they're due.
