If you have been around for a while, you will have a treasure trove of collected memories—stories and images that live in the recesses of our minds—units of time with which we are loath to part.
Our lives are made up of millions and millions of units of time that flow from one into the other. Some stand out, many fade. From time to time, we call up a favorite so as to relive a story for which we have a particular fondness. Sometimes memories come flying in all on their own, triggered by some wisp of something we barely perceive. A smell, a sound, a pair of old shoes or a song from the past—really anything can trigger a flood of sensory memory—and all the longing and bittersweet thoughts that come with it.
