Here, my sweet child, I lay you down to rest. Sleep away and begin to dream, wherever or whenever that may be.
You'll be a knight, courageous and strong. You'll defend what's right and wrong. You'll be an explorer of the deep. Who knows the treasures that you will reap? You'll be a time traveler and careen into the past. You'll gain great knowledge and have a blast, at coming back to the future and making it last, by saving the dreams of other children that have been dashed.
Or, perhaps, greatest of all, you'll become an astronaut brave and tall. All you need is the will to try, so flip that switch and away you'll fly. Quickly, you'll fly past Mars, and soon you will be caught in the stars. Just like them, you will shine, and remember that you'll always be mine.
So, alas, little star-sweeper, I have to go. You need to rest and dream, you know. But don't worry, you'll never be alone, for you are with me, and we are home.
