Perhaps every generation of geezers since Adam and Eve has whined about young people, and today is no different. Isn’t it clear that in contrast to our glorious selves, kids these days are self-absorbed Facebook junkies just a pixel deep?

No, actually that’s wrong at every level. This has been a depressing time to watch today’s “adults,” whose talent for self-absorption and political paralysis makes it difficult to solve big problems. But many young people haven’t yet learned to be cynical. They believe, in a wonderfully earnest way, in creating a better world.

In the midst of this grim summer, my faith in humanity has been restored by the saga of Rachel Beckwith. She could teach my generation a great deal about maturity and unselfishness — even though she’s just 9 years old, or was when she died on July 23.

Rachel lived outside Seattle and early on showed a desire to give back. At age 5, she learned at school about an organization called Locks of Love, which uses hair donations to make wigs for children who have lost their own hair because of cancer or other diseases. Rachel then asked to have her long hair shorn off and sent to Locks of Love.
