In this sweet, thoughtful story, a little boy feels unhappy when he compares himself to his classmates. But he comes to realize there's a lot more to a person than just what they're good at. Just like all the beautiful different pebbles he finds on the beach, each person is amazing in their own unique way. And that's a thing to celebrate. He shares his new knowledge by giving each of his classmates an award for being themselves. If you're ever feeling sad like I was, he says, just remember, you're the very best at being YOU. In doing this, he actually finds something he is very good at indeed - and that is being a very kind friend.
