If you aren’t careful, it is very easy to get pessimistic these days. We have gotten too loud, too adversarial, too politically-correct, too ethically-challenged, too secular and too narrow-minded — not to mention slightly humor-impaired. Just when I think that maybe this world and those that occupy it are beyond redemption, I run across someone like Ava White and I am reminded that there are good people quietly doing good things for all the right reasons.
