Harry Potter lay in bed on the eve of his 17th birthday, watching his clock for the second it turned 12. "8… 7… 6… 5… 4… 3… 2… 1… Sweet!" Harry jumped up and grabbed his wand and ran into his cousin Dudley's bedroom.
"What the…" Dudley started, the stopped as he saw Harry with his wand in his room. "Your not t-to do th-that stuff.. D-dad said y-your n-not allowed, or y-youll get ch-chucked out of your sch-school…" Dudley stuttered.
"Sorry duddeykins, I'm seventeen now, so I can do whatever the hell I want to." Harry said calmly. Dudley went all rigid, then ran from the room as fast as his chubby legs would allow, screaming for his parents at the top of his lungs. "Impendimenta! Silencio!" Harry said as he walked lazily over to his cousin. "You see Dudders, I can do whatever I want now. There's nothing you can do to stop me."
Just then, Harry's aunt and Uncle ventured out to the scene, and froze. "Argh boy! What the devil did you do to my son!" Screamed Uncle Vernon. "You're expelled now, boy! You can't use your.. your.."
"Abnormality!" Finished Aunt Petunia shrilly.
"Ah, you see, that's where you are wrong. I am an adult now, see? I am seventeen, and can use anything I want to. In fact… petrificus totalis. I have SO been wanting to do that for years.." Uncle Vernon had fallen to the floor. "As for you, auntie.. stupefy! Haha.. I feel good."
