The Ring of Three: Mother Minus 10

After a moment, an idea came to Jake. He pointed the ring at the mother and said "Ten years younger." That same green glow emanated from the ring and surrounded the thirty-year old woman with the same green glow. And just a moment later, she began to grow younger. It wasn't quite as noticeable as the girl's change, but the mother (was she even really the girl's mother anymore?) was definitely becoming ten years younger. The two college-aged girls laughed about something they were talking about, then moved on towards a women's clothing shop, as if nothing had changed.
