When Jon got back to his room, he grabbed the stone. He figured that if he had a magical stone that could grant almost any wish, why not use it to get ready for school? It would surely take up a lot less time. And free up more time for Jon to spend with his friends.
He made a wish, being very specific about what he wanted to wear, and then it was granted to him.
Jon looked in the mirror and smiled. He was wearing his typical school attire (or so he thought): a pink halter top, a denim miniskirt, and a pair of pink 3-inch heels. He looked so cute in this outfit. He quickly applied some make-up that he wished up and put some earrings (also that he wished up - for some reason, he couldn't find the ones he already owned) in his ears, then smiled again. Yeah, he was hot.
He turned around and looked for his purse, but for some reason he couldn't find it. He could have sworn that he left it next to his bed. He shrugged. He could just use the stone to wish that he had it. And that's exactly what he did.
Once he received his purse, he swung it over his shoulder, then left for school.
