When a bird sings for the first time, a child breathes it's first breath, a new present is opened, you learn to forgive, you travel, you hang out with best friends, silence fills a noisy room, you find true love, you learn something new, you eat your favorite food, you can move on with your life, somebody has a positive attitude, you can react positively to a negative situation, you learn how to be humble and serve others, your friends don't want to change anything about you, you have a good day, or when you smile that's something beautiful.
Smiles are beautiful. So are you. That's something to smile about and that's something beautiful.
