There's nothing quite as healing and restorative than nature. Last summer, when my wife was very ill and in a wheelchair, I would wheel her down to the neighborhood park. We'd spend hours feeding the squirrels. It got to the point where they recognized us and would eat from our hands. We began to realize each had their own unique personalities and were much brighter than we thought. All we had to do was whistle and dozens would come down out of the trees towards us. That was a magical summer, what turned out to be our last in the city.
