It goes without saying that Stephen passed before his time. My heartfelt wishes go to Betsy, Stephen's wife, as well as his son Matthew.
I am reminded of this sculpture of Memory by Augustus Lukeman (photo by Lee Sandstead). This work was made in honor of Isidor and Ida Straus who lost their lives during the Titanic disaster. The statue of Memory does not ponder the tragedy of the Straus' loss. Instead, she thinks of the good lives that they lived and their continual love and warmth for each other while alive. It is a monument dedicated to fondness, and not suffering and sadness.
It is my hope that over time, such a sentiment can warm the hearts of those affected by Stephen's passing.
