Mikey took the trash out anyway, laughing to himself that Jon still looked very girly as he got younger. It might be fun to have a little sister to tease.
At that moment, Jon was 13 years old. But when Mikey came back into the house, he saw that Jon had regressed further, looking more like Mikey's own age of 10. He must have been making fun of me while I was outside with the trash, Mikey thought. That jerk! Not only does he do it to my face, but also behind my back.
Mikey looked at the 10 year old girly Jon, whose clothes didn't fit very well, as they were baggy and loose. But thanks to Mikey's wish, Jon didn't think anything was strange about his clothes or the fact that he and Mikey were the same age.
