Jon waited expectantly for something interesting to happen. Nothing. He was tempted to use another wish to find out what it was, but decided it would be fun to find out on his own. A short while later, he was in his bed, fast asleep, his careless wish almost forgotten.
The next morning, he habitually went downstairs and poured himself a bowl of cereal with milk; it tasted a little strange, but he was too sleepy to care. As he finished, his little sister Zoe walked in. She took one long look of disbelief at Jon and the empty carton of milk still on the counter.
Tears started to well up in her eyes as she yelled, "Mom! Jon drank my milk!"
Jon's mom came rushing in. She also stared at him in disbelief. "Jon, what have you done?"
Zoe ran to her and sobbed. "I had been saving it for weeks. I have that dance tonight and now it's ruined." Jon's mom comforted Zoe while shooting daggers at Jon.
Jon was incredibly confused. He figured the wish did something to the milk, but he had no idea what. Suddenly, his stomach started to churn, like his insides wanted to be on the outside. He grabbed his stomach and moaned, "I don't feel so good."
"Of course you don't," Jon's mom replied harshly. "You drank somebody else's milk. On top of that, you're a guy. Now, go upstairs while I think of a good punishment for you. Also, you better start thinking of a huge apology for Zoe."
Jon obediently went upstairs, still confused and in pain. He grabbed the rock and said, "I wish I knew the the effects of my previous wish." A flood of knowledge flowed into his head.
