“Maybe you have to be a grandparent to realize how neat kids are. Sometimes they’re bundles of energy gift-wrapped in hand-me-downs. Other times they’re pajamaed packages of sleepy sweetness. Always they’re a miracle. I love the way they chase butterflies, and I love the attention they give to mud puddles and raindrops on a window. I envy their freedom from clocks and calendars, their immunity to pressure. Oh, they have their moments, skinned knees and nap time, but they recover quickly. They don’t nurse their disappointments or make a career out of suffering.”
