"I wandered lonely as a cloud," wrote William Wordsworth. Though his cloud floated "on high o'er vales and hills," mine was perched in a perfect blue sky above a sand dune. 

How solitary it looked, this cloud, how out of place, as if it had stumbled into the wrong act of a play. 

Where were its compatriots? There were other clouds in the sky that day, but nowhere near this one, which had dared to move inland instead of out to sea. 

Its out-of-placeness only emphasized its ethereal boundaries, its contrast of white with blue. It looked like the dot of an explanation point, punctuating a late summer day.
