Seraphic Secret has an excellent and heartbreaking post about going through the notebooks of the son he lost.
Elie's Expositions has three articles also about the pain of losing his son last year, and his latest is both saddening and uplifting.
May both Elie and Robert take comfort in the fact that they and their wives raised incredible young men who continue to touch and inspire all of us.
In this Pesach season may we only have שמחות, happiness, and may we go מעבדות לחירות , from slavery to freedom, in every sense of those words.
