In this I was aided by landscape. What is it about a glimpse of long distances that airs out the brain?
There is one spot on the road we took yesterday, one that approaches the area from Maryland rather than Virginia, where the view must be 50 miles or more in either direction. From that vantage point, it's easy to see how small we are, how busily self-important.
Spend enough time in the company of grand landscapes, and the trivial falls away.
