At seventy years old, I thought I had already experienced the greatest joys and deepest sorrows life could offer.

At seventy years old, I thought I had already experienced the greatest joys and deepest sorrows life could offer.

I had buried my husband after forty-two years of marriage. Three years later, I buried my only child and his wife after a terrible car accident left their seven-year-old daughter, Harper, in my care.

Since then, it had been just the two of us in the old white house where my husband and I had raised our son.

The paint was peeling. The kitchen faucet dripped at night. And every month, I sat at the kitchen table with a stack of bills, trying to decide which necessities could wait.

Sometimes, that meant postponing a prescription refill.

Sometimes, it meant putting off buying Harper new shoes, even when her toes were beginning to press against the ends of her old ones.

But somehow, that little girl always found a reason to smile.
