When our kids were young, my wife Martie and I enjoyed family vacations in Florida visiting our parents. It was especially wonderful to be there in the warmth for a brief respite from the Michigan wind-chill factor. I couldn’t wait to just relax on the beach with a good book. But my kids had other ideas. They wanted my help building sandcastles. Reluctantly, I’d get up to help, only to be quickly consumed by the project at hand.
