I've written a lot about ageism. About how people don't value the contributions of seniors. About how long-term care residents are invisible and forgotten. About kids these days, and why they don't respect their elders. As raving tangents go, I'm generally not bullish on the prospects for societal culture change. But after recently traveling to Washington, D.C., with 10 World War II veterans and their 14 caregivers, I might have to reconsider.
