In "The Writer in the Family" by E.L. Doctorow

Aunt Frances was moved to tears by Jonathan's first letter.

My aunt called some days later and told me it was when she read this letter aloud to the old lady that the full effect of Jack’s death came over her. She had to excuse herself and went out in the parking lot to cry. “I wept so,” she said. “I felt such terrible longing for him. You’re so right, he loved to go places, he loved life, he loved everything.”
