The one thing that teenagers with a wishing stone never realize is that they potentially have a long, long life ahead of them, so making permanent wishes with conditions dependent on only one other person can effectively both bond and bind you together for decades and decades.
Fortunately, when one of those permanent wishes allows you to repeatedly make small adjustments to one member of the couple, it's much easier to resolve differences and arguments, and for one side to understand the other's point. The binding enables the bonding. And a friendship turned into a relationship becomes a life-long team.
Jon and Karyn finished the school year without seeing Sarah. They knew it was a possibility, as much as they hoped it wouldn't turn out that way. Years later, they heard through the grapevine that a cheerleader named Sarah was graduating high school, and they both hoped it was her, but they thought it best to leave it be, just in case.
Every Friday night became a routine for the two of them. The copied features that Jon had accumulated throughout the week that neither of them thought were good ones to let take hold, would be enabled one by one so that Karyn could readily cross them off. Any features that had been allowed to set in early were reviewed and discussed, and then either left in place or crossed off as well.
It allowed for an adventurous life. There was the concert they went to where the lead singer yelled out to the crowd, "You all are at this low energy level right now, but I need you to get way up here!" Jon and Karyn looked at each other, smiled, allowed the copying to kick in, and Jon spent the rest of the show on stage as a backup singer playing the tambourine. There were the endless times at college where someone told Jon, "You need to try it!" and for a week or longer, he would. There was the time at their wedding rehearsal dinner when Karyn's mother told Jon, "You need to take a step back and just enjoy today," and Jon and Karyn accidentally let it take hold until Karyn realized why Jon was acting so strangely maternal during the meal. There was the time that Karyn, in discomfort, snapped at Jon, and he willingly carried their child for the last four months. There were the endless opportunities to copy skills or knowledge or features that kept them infatuated with each other and kept their sex life refreshingly new and vigorous, to the general jealousy of their friends.
The notebook never ran out of pages, and was always kept safe.
The wishing stone got used from time to time, but rarely worked in the way that they intended, so it became a break-glass-in-case-of-emergency tool rather than a toy. The copying provided plenty of regular entertainment by itself, anyway.
And much later, when their grandchildren came to visit, a simple excited comment from a toddler often gave Jon the energy needed to play right alongside them.
It was a good life. Sometimes things work out that way, even accidentally.
