In "Everything I Know: Lessons for Life, Love, and Laughter," author Megan O'Neill shares stories about one of the most influential people in her life: her grandfather, Elmer Marocco. From lessons in what good music is, to how to make the perfect roasted red peppers, to what it means to love and be loved, this is a collection of stories that spans twenty-two years' worth of companionship, adventures, and the occasional bout of mischief.
