"I am your big sister, remember?" said Melanie.
Although I liked her really, she can be quite bossy at times and I often wished I was the eldest instead on her. Now I can be!
I made my wish and Melanie started getting smaller and younger. By the time the changes stopped she was 15, a year younger than me. Seeing her reflection in the mirror, she gasped. "Oh my god! I suddenly look like I've lost a year or so! What happened!"
I decided to tell her. "I got this magic ring today. It made your clothes momenterary vanish and now made you younger than me. Guess I'm your big brother now, sis!"
"Don't call me sis!" she yelled "I want to be bigger again!"
