Yes, it has.

Sarah looked down at herself, but from the blank expression on her face, Tom could tell she wasn't seeing what he was. She gave him a weird look, so he tried asking her, "Honey, how old are you right now?" The answer before he'd rubbed the coin would have been 39, but if she really didn't think anything was different, she might give a very different answer.

Giving him a look that made it clear she thought that Tom was getting heat stroke or something, she said, "I'm 29, remember?" Then she let out a sigh, and started looking into the middle distance. "I can't believe I'm going to be thirty soon, I'm going to be so old." AS always when hearing anyone younger than that say it, Tom couldn't help scowling, and Sarah noticed her mistake right away and tried to pull a recovery. "Not that you're old or anything, Tom. Gosh, that was really rude of me to say."

Having already felt like he was on the right track, Tom tried one last time to really confirm his suspicions were on the level. "It's okay honey." Then, he managed to find a way to ask what he wanted without sounding like a crazy person again. "It's crazy to think how long ago we got marries, isn't it? You were...how young were you when we finally got hitched?"

She shared a nostalgic smile with him, before saying, "I was nineteen, fresh out of high school really. My parents said I was crazy for marrying you, but they came around eventually. We knew we were right for each other, right from the start." The bottom fell out of Tom's stomach. So, the coin had completely changed her memory of their marriage. Had it changed everything else as well? Had reality completely changed to fit the new her?
