We drove six hours, barely speaking. The house was small and tidy, and a thin, gray man opened the door before we knocked. My father, Walter, wept when he saw us. He said he had left twenty years earlier after losing the family savings in a gambling debt, then spent two years in prison for fraud. He was so ashamed that he let me believe he had died, rather than face me.

Walter explained that he had quietly followed our lives through an old neighbor. He had begun sending the cards the year Caleb turned one, using every spare dollar from his janitor’s wages. Each year he wrote a letter and never mailed it, afraid I would throw it away. This year he finally found courage after a doctor told him his heart was failing, and he wanted to meet his grandson before it was too late.

I was angry, and I told him so, with tears running down my face. But I also saw an old man holding a shoebox filled with copies of every card he had sent, each with a note about what he hoped Caleb was doing that year. Caleb read them one by one in silence. Then he hugged his grandfather, and I finally felt my anger loosen.

Walter lived another eighteen months, long enough to attend Caleb’s first college football game from the front row. We buried him beside my mother, and Caleb read the final card aloud at the service. Now every birthday, Caleb mails a plain envelope with a ten-dollar bill to his grandfather’s grave, signed with his name this time.
