"I will tie balloons to my arms, legs and neck, and they would lift me above all the houses until I reached the stars. Then I will sit on the moon and wave to everyone down below, but they won't be able to see me" she answered. "Now that's just silly Grace, how do you expect that balloons would be enough to lift you off the ground?" her teacher replied. "Well there would be LOTS of them." "And how do you plan to sit on the moon? Gravity wouldn't allow it" "Well I would tell gravity that he isn't being very nice and that best friends don't 'not allow' each other to do things and I promise to be best friends if he lets me sit on the moon". "Gravity doesn't work like that" "Well he should"
After 85 years of tying balloons to herself, Grace was finally lifted above the houses until she reached the stars. She became best friends with Gravity. He wasn't so bad after all, and he did allow her to sit on the moon and wave down to everyone below, but they couldn't see her.
