Although Mark was perfectly aware of what had happened to himself, he nevertheless found his new personality felt... natural! He knew he was now behaving like a thirteen-year old girl, but he discovered he didn't care. He also discovered that he didn't really have any desire to get back his original, teenage boy personality (which was now in the mind of Old Man Nicholson from next door).
Giggling again like a middle school girl, Mark watched as his sister Heidi shuffled back out into the living room. She was now dressed in their dad's clothes, her tiny body practically swimming in a polo shirt, pair of dockers, and a pair of his brown loafers.
“Consarn it!” growled Heidi. “I'll have to go buy myself some decent clothes after school today. Can't believe all I own is frilly, girlish garbage! Dad won't mind me borrowing his clothes, though. After all, he don't want his daughter looking like some kind of cheap, French hooker!”
Mark giggled again. It was incredible. Heidi still knew she was Heidi... but now felt compelled to think and act like an elderly man.
Mark, still thinking and acting like an immature middle school girl, couldn't wait to take this little technological toy to school and have some real fun with it!
