knowing

As I pushed the shopping cart down the long, long aisle, I was suddenly aware of a sadness, a heaviness stealing over my soul like frosty air swirling in through an open window.
It has always amazed me that feelings can surface out of the blue.
I had no idea what strong emotion was there, just below the surface and why being in a grocery store would trigger it.
And then, like watching a figure appear out of the mist, I suddenly knew, and in that exact moment, tears sprang to my eyes and my hand flew to my mouth.
Then I understood and somehow, just the knowing comforted.
