“I can’t do this anymore.” That was the opening line of the letter, her grandfather's words, scrawled in hurried handwriting. Clara sat on the floor, surrounded by boxes of her grandparents’ things. The letter was a draft, never sent, a secret her family had kept. The words seemed to jump off the page, demanding to be acknowledged. A numbness spread through her limbs, making it difficult to even move. The letter felt accusatory, a reminder of opportunities lost and dreams abandoned.
