The Story of Harold Hydrogen

I Just Want to be Alone

My name is Harold Hydrogen and I have never been alone. I'm currently with Oscar Oxygen and my cousin Hannah Hydrogen, and he just won't let us go! We have an uncle, Hector Hydrogen, who's escaped him before. He didn't come out un-scarred, but he got to be alone. My whole life I've spent connected to someone, I just want to be alone.


Today is the day it all changes, I'm following my uncles footsteps. I know the dangers of being alone, and I'm willing to take the risk. We're taking Oscar to a secret place. Little does he know, it's temperature reaches an unthinkable high, and he'll have to let me go!


We're almost to our destination, I can feel it getting hotter every step we take. I'm so close to freedom, I can barely belie-- Oh my gosh! I'm free, I'm fr-- Ouch! Ouch! I'm on fire!
