Over the last few years I have been reading my great-grandfather's journal, yearning to know his soul. His entry for April 2, 1892 had a real impact on me: “I received a letter from Mother but no letters from my dear family & on this account I was very sad & uneasy.” I pictured my beloved forebear far from home feeling anxious and lonely. I desired to provide him a letter. My heart proclaimed: “I will write him!” even as my mind wondered how to send a message to the past.
