"Please read this," my three-year-old Claire said one day, pointing to a page with an old children's song: "Do you know how to plant cabbages". In blue ink, someone had crossed out cabbages and written "Watermelons!" "Daddy! Did you do that?" Claire asked, looking up with an expression of shock.

As Claire planted the seeds happily, I watched my grandfather's joy take fresh root in her life. And that was the biggest miracle of all. Claire was shocked at the mark on the page because  _  .
