I treasure our memories together as cousins. We'd likely only see each other a couple times a year as kids, but at Christmas, we'd always compare our gift haul. Later, we didn't see each other quite as much, but I knew your family was 'just down the street' in Bethesda. The Sullivans were always generous with their house and their time with our little Get-Togethers. On a personal level, I was always envious that you got to see the Beatles perform, and I didn't. Dennis, on wings of Angels, Ernie
