When Jon woke up the next morning, he immediately grabbed the stone. Why bother going through all the trouble of getting ready for school when he could just wish for it?
He sat up in bed and said "I wish I had all my clothes on for school and was ready to go." The stone glowed, but instead of white light, it was an eerie blue light.
"What the ..." Jon started to say, but stopped as his body collapsed into a pile of clothes, the clothes he was planning on wearing to school that day.
